Marshall Amplification 1959RR User Manual

From Jim Marshall
I am reallypleased that you have chosen this 1959RR Randy Rhoads Signature Series Super Lead 100W head. It is only the fourth signature amplifier that we have produced and I feelit is a great addition to this selectrange.
I first met Randy whenhe came tothe factory in January 1980.He had not long ago joined Ozzy Osbourne and they were workingon theirfirst album. He came hereknowing exactly what hewaslooking for, he just needed to find the amplifier thatwasgoing tobe capable of delivering thepower,the tone, and thereliability that hewanted, but was alsoin keeping with theimage thathe was to be recognised by.
Randy almost found everything he was searching for inastandard1959 head, but the tone was not quite right. He spentsome time with my Service Manager, explaining theslight differencehe was lookingfor, and afterafew trials we wereable to fit a modificationwhich made the subtle change to the standard toneof the1959.
Randy left thefactoryto proudlystand infrontof his whiteMarshallstack for all of his hugely successful, but sadly too brief careerwith Ozzy Osbourne.In this time the legendary guitarist couldbe seen by thousands of fans,performing in front ofhisMarshallstack – a sight to behold and a triumphant assault on theears.
Our design team havespent many hoursinvestigating the original Randy Rhoads amplifier, speaking to the Randy Rhoads family, talkingto people who knewRandyand heard him play, and talking to the ServiceManager who was atthe factory whenRandycame in and made themodification tothe amplifier.The resultof all this hardwork is the amplifier you have just purchased – based onthe classic whitehead that Randy bought in1980.
As withall MarshallAmplifiers,when you plug intothe 1959RR, whether onasmall or large stage, you can do so with theconfidencethataccompanies all of our products,
Yours Sincerely,

Dear Randy fan,
I sincerely hope that your Limited Edition, white Marshall Randy Rhoads Tribute ampgivesyouas much pleasure as the original gave Randy. I canremember him callingme from England the dayhe wentto theMarshallfactoryto get it and hewasso excited about it hejust couldn’t containhimself. He’d justspent the morning thereand he said,“guess what?They’regoing to modify it for methe exact way I want it!” Healso told methat it was going to be whiteandhe was very excited aboutthat toobecause he really wanted itto bethatcolour. He was completedelatedaboutthe amplifier being customised personally for himandhe was also totally enthused by hisvisit to Marshall. He just wenton and on about how great itwasto see everythingthatwent onthere and also meetsome of the people behind the company!
The fact that somany people still listen toRandy’s music and somany young playersof today cite him as a major influence makes mevery proudandIreally appreciate it. Randy really loved the Marshall soundandMarshallwasdefinitely the amplifier tohave inhis eyes – especially a whiteone! I thinkit is just greatthat Marshall have done this specialamp in honour of Randy’s memory because it lines him up there with all thegreats. Thisis a huge compliment toRandyandIam extremelygratefulto Dr.Jim Marshalland his company for doingsuchaprestigious thingin my son’sname.
Randy achieved such a lot in a very short time and I hope thatthisamplifier will inspire your playing asmuchas it did his! Sincerely,
I did something you'll appreciate - I went to the Marshall factory and ordered my own amps, I had them beefed up and modified there, I got them in white! A stack is
really cheap here! I got a stack for $500, brand new, so I bought two of them, the ones I was using were rented and it was costing more money than owning them.

Randy Rhoads was more than just a guitar player – he was a lion! He represented the hardworking musician whose dedication to his instrument brought him all the success
that he deserved, without compromising his attitude and vision or his sound and tone. He also laid down the blueprint to show us how to follow our own vision as well.

From Randy's fierce playing to his dedication as a musician, he was and still is an inspiration to me in all ways, not just as a guitarist.

I can’t say enough good things about Randy and the influence he had on me, especially when it came to orchestrating. The classical vibe he had was incredible. I loved Randy’s brittle sound and his awesome ability to
double his leads. There’s no telling what that cat would be busting off if he was still around. He was a monster player and his guitar work on “Blizzard of Ozz” and “Diary of a Madman” was definitely one step above anything else going on at that time. To me, Eddie Van Halen was heavy rock ‘n’ roll, but Randy was heavy metal.
DimebagDarrell (RIP), Pantera, Damageplan
I was 13 when I first heard Randy playing on the live 'Tribute' album which is still my favourite Ozzy release and always will be. The way Randy played rhythm and threw in those gnarly licks in-between just blew me away. I was already familiar with players like Steve Vai
and Yngwie Malmsteen but there was just something about his sound that was something else.
He's definitely been a big influence on my playing... and how I like my guitars shaped! Each note he played served the music which is what makes a great guitarist... and that was Randy.

Randy Rhoads: Tribute to a Timeless Talent
“There are some peoplewho are like a shooting star. Theycome, hit the planet and explodeinto a beautifulrainbow of colours. Then theyshoot off somewhereelse... thatwasthe life of Randy Rhoads.”
The source ofthese touching, eloquent words? Believe it ornot, they’re directly from the mouthof hard rock’s most beloved madman,Ozzy Osbourne – taken from an interview he did with Guitar World magazine a few years ago. Intruth, to anyone whoknowsmore about Ozzy than the often shocking image the populartabloid press liketo portray, this sort oflyrical waxing by the legendary heavymetal artist willcome as nosurprise, especially when itcomes to Randy Rhoads. After all,the singer consideredthe late, great guitarist to have not only beenhis“best friend” but also “the greatest musician I have ever known.”
Ozzy isnotalone inrightfully considering Randyto beone of themost extraordinary musical talents in thehistoryof rock – onlyahandful ofplayers are as beloved and revered as he is. Inthe space of a mere two studio albums with Ozzy – 1980’s Blizzard of Ozz and1981’s Diary of a Madman – the guitarist establishedhimself asoneof themost innovativeand inspirational rock guitariststo everwalk this planet. Furthermore, despite theheartbreakingfact that Randy was taken from us at the tender age of only25, the timeless nature of his talent continues to inspire countlessyoungplayers some26 years later... such is the size of theindelible shadowRandy cast andthe colossalimpactof his brief but brilliantcareer.
What makes Randy soveryspecial? Well, likeall timelessmusicians itwasn’t only his incredible playingbutalso his profound skills inthe areas of composition and arranging. Simply put, the songs he wrote with Ozzy are as fresh sounding and exciting today as theywere whenthey were first penned. Add to that Randy’s brilliantrhythmwork, his jaw-droppingsolos and leadfills, plus his trademarkpenchant for successfully blending his classicalsensibilities with hard rockandyou’re left with the stuff that legends are made of. AsZakk Wylde, Ozzy’s current, longstanding six-string sideman andaguitar Godin his own right, soaptly puts it in his heartfelt,handwritten introduction to this tome: “What more canIsay? Randy had it all,still has it, always had it–beyond forever,always will. Without Randy I wouldn’t be the player I am today –the chops, thewriting and that amazing fatherMarshall tone.” And Zakk isn’t alonewith such sentiments – as you willseefrom thequotesthat pepper this piece, Randy influenced a wholegeneration of cutting-edge players whoare now influencers themselves.From the likesof Kirk Hammett & Kerry Kingto Dimebag(RIP), John 5 & Alexi Laiho (Children of Bodom),Randy’s influence is omnipresent...
Talking of omnipresent entities: to a greatmany folk,Randy’s beloved, large logo,white Marshall100 Watt SuperLead head is as synonymous withthe guitarist asis the unique whiteJackson guitar hedesigned(aside fortrivia fans – this axe was originally namedthe “Concorde” by Randy and co-creator, GroverJackson). As the engineer ofBlizzard of Ozz and the producer/engineer ofDiary of aMadmanandthe posthumously released live Tribute albums, Max Norman, recently toldus about Randy,“heinsistedon no compromises for his amplification. There's nodoubt in my mind that his Marshall amps and cabinets not only accompaniedbut assistedRandy in his climbto greatness.” As a fittingtribute to Randy, the 1959RR head you’re now theproud owner of is not only visually identical to his legendary Marshall, it is also sonicallyidentical aswell.
Marshall’s meet up with Kelle Rhoads for a technical assessment of Randy’s Marshall gear
It was my pleasure to assist Randy in this very joyful occasion, at Musonia School of Music in California; it was just me and the Signature Series Development Engineer from Marshall Amplification, we were in the room where I teach my students, and one by one the amp and cabinets that belonged to Randy, were pulled from their road cases and thoroughly scrutinized.
As revealed elsewherein this manual, when Randy ordered his now famous whitehead, he visited the factory to pickit up and had itmodifiedfor more gain while he wasthere.Thanks to the Rhoads family, one of our engineers was allowed to take a detailedpeak inside Randy’s original head (wisely kept underlock andkey in a vault inan undisclosedlocationalong withhis equally famous guitars) to ensurethat the Tribute amp was electronically identical to it. As a further bonus we were alsoable to speak tothe Marshall testmanager who didthe modification while “the smallblokewith a white Les Paul” patiently stoodby and waited! The modin question?It simply cascades the two halves of thefirst ECC83 valve, givingyoualotmore preamp distortionthan in a standard 1959 Super Lead head. ChannelI(a.k.a. the “HighTreble” channel) remains“asis” but whenyouplug into Channel II (theso-called “Normal” channel) both Volumecontrols (I & II) worktogether intandem (series) to producethe increased preamp overdrive desired. The result? Well, toquote Zakk again,“Father Marshall tone” indeed!
Randy was so happy with his visit tothe Marshall factory and the amphe left with that heactuallypenned thefollowing inapostcard to his friend and ex­band mate, Kevin DuBrow–the recently deceasedsinger forQuiet Riot. "I did something you'llappreciate–Iwent to the Marshall factory and ordered my own amps,Ihadthembeefedup and modified there, I got them in white!”
Randy enteredthisworld as RandallWilliam Rhoadsin SantaMonica, California, onDecember6th 1956. To sayhe was born intoamusical family would be a gross understatement as his beloved mother, Delores, ran a Music School in North Hollywood named Musonia -afine institution she still worksin everyday at nearly 90 years young!Randystartedplaying guitar at the tender age of 6½ after findinghis Grandfather’s old Gibson acousticin a closet.“He justpicked it upandthat was hislife from then on.” Deloresrecalls with a grin.“NaturallyIhad him starttaking lessons from one of my guitar teachers–he learnedafewsimplechordsandthey would play some of those songsthat he especially liked.”
Even though one of hismost magicalmusical moments is the shortacousticsolo piece“Dee” (namedafter and dedicated to hismother, Delores)on Blizzard of Ozz, Randy didn’t stick with theacoustic long.“By the time he was seven he came tome and said,‘you know Momma, I really wantto play electric guitar.’” Delores laughs.“I had a very good teacherat that time so I said fine but the onlyinstrumentwe had was anold semi-acoustic andthe guitar was almost larger thanhe was!”
Armedwithhisbehemoth instrument,Randywasanatural and developed asa player incredibly quickly. “He learned very fast,it was just amazing.” Delores confirmed.“Thestory about histeacher, ScottShelley, saying tome,‘I’ve taught him all I know I can’t teachhim anything more’ has beenwritten up in themagazines quiteoften.Isaid, ‘Come onScott,’ because I thought he was teasingme but he toldme that hereallymeantit. So then Randy had to takeit upon his own selfto do whathe wanted to do,which hedid.
“He just loved the guitar,” Delores continues. “That was hiswhole life. He wouldn’t goanyplace without his guitar - if we went on a vacation,we had to take it!”Alongside his love forthe guitar camean affinityfor rockmusic after his olderbrother, Kelle, tookhimto an Alice Cooper concertwhich,as Mrs. Rhoads recalls with a smile, “impressed Randy a great deal and influenced him to get really interested inrock.”
Randy was so happy the day he got to go to Marshalls and pick this equipment. Well, here we are twenty five years later with the very same gear, except the black stenciled name on the boxes is not just a touring guitarist name anymore; it is the name of one of the world’s greatest Icons. I could feel his presence that day, laughing and smiling while the Marshall engineer worked over the circuit board and sweated to make sure everything was 100% accurate.
In the end standing on the porch of Musonia, as Randy and I so often did, smoking a cigarette (so appropriate if you knew Randy) the Marshall engineer and I said goodbye and off he went back to England… and I was left with special memories of Randy and his amps once again.

Talking of Alice Cooper, while the likesof Jeff Beck, LeslieWest (Mountain), Jimmy Page, Ritchie Blackmore, MichaelSchenker(UFO, MSG)andMick Ronson (David Bowie) are often cited as being majorinfluenceson Randy, one that israrely mentioned but,according toclose friends, was a huge source of inspiration on thethenfledgling guitarist, was AliceCooper guitarist,Glen Buxton.Detourover, back tothe mainplot…
Needless to say, with his God-givengiftfor guitarand his incredible drive, Randy’s playing continued to improve inleaps and bounds. Not surprisingly, given his surroundingsand the fact that he’d learnedall he couldfrom his mother’sbest guitar teacher, by the time he was a teenager Randy had became a teacher at Musonia. And Randy was notjust a good teacherbuta great oneandincrediblypopular with his vastlegion of guitar-worshipping disciples. “Randy was not only a legendaryrockstar, I also consider him asan outstanding teacher,” states RudySarzo,the brilliantbassist who played alongside Randy in his first bandQuiet Riotandthenwith Ozzy. “He actually taught me to be a better teacher.Iwasteaching bass at Musonia and oneof thegreat things about his teaching methods was his ability to listen tohis students. He wasn’t one ofthose,‘this iswhat I want youto do, don’t ask me any questions,’ guys, hewouldactuallylistento his students and bydoing so he would getto find out theirspecificneeds and really honein onthem.
“He also told me once that hewouldlearn a lot by actually watching and listening to hisstudents play,” Rudy continues. “Sometimes naturalmusicians have different ways of doing things – likethe way theyhold thepickor position theirleft(fretboard) hand. He would lookcarefully atthe way natural playerswouldhandle their instrument and learn from that.”
“Randy was a reallygood teacher,”Delores confirms with understandable pride. “He always passed on hislove for music and encouraged his students to be as dedicated and musicallycurious ashe was. He also made the students feel really important and hewouldalways end up the lesson byplaying with them.And, of course, they all came out on cloudnine as theythought they were the good ones.”
After running the usual gamut of garagebands, Randy formed his first real band,QuietRiot, andby the mid ‘70stheoutfithad become the houseband at theStarwood, an infamous Hollywood rockclub. Sarzo joinedthat in 1978, a year before Randyleft to joinOzzy Osbourne and commencehisrapidrise to rock stardom. Ironicallythough, the Ozzyaudition nearly didn’t happen… “When they first called Randy to audition for Ozzy he said, ‘Oh I don’t think I’d be interestedbecause I work formy MomandI have my own band which I like.’” Delores recounts. “Hewasn’t even goingto go. I said, ‘What was that all aboutRandy? Who was that?’I didn’t recognizethe name Ozzy Osbourne becauseI didn’t knowanything aboutthe rock sceneandRandy explainedto me that he had been in the businessfor a long time witha band called Black Sabbath. He also said,‘I reallydon’t care for that band at all!’“
“So I said,‘Well if he’s been in the businessthat long sometimes that’s a good thing. Who you know is importantas that can give you a little inlet or something that helps yougetfurther alongin the industry.’Anyway, theycalled back and said, ‘We reallydo want you to come to audition’ and Randy told them it wouldhave to be latebecause he would be teachinghere first and didn’t want to let his students down.They saidthey didn’tcare how late it was and it ended up that he wasn’t gone all thatlong at all. He came back much sooner than I expected. ‘Well, what happened?’I askedand he said, ‘Oh I don’tknow. I wasjust warming up a littlebit andtuning up when Ozzy came out andtold me I’d gotthejob!’”
As legend now hasit, apparently Ozzy was sleepingon a couch in the rehearsalroom and whenhe initially wokeup he thought Randy wasa girl! Then he heardhimplay and literally knew within seconds thathe’d found the guitarist of his dreams. “Building the bandwith Randy was oneof the happiest timesof my life,” Ozzy wrotein the sleeve notes of the 1987 Tribute album. “He helped make allmy dreams come true.”
What happenedonce OzzyandRandyjoined forces is now part of heavy metalfolklore andhasbeen documented countless times. Alongside Ozzy, Randy came intohisown and histremendous talentsliterally tookthe rock worldbystorm.“I always tell people thatI played with twodifferent Randy Rhoads,” Rudy Sarzo states. “The one I played with in Quiet Riot was a chameleon.We were always tryingto pleasethe record companiesso we’d always try andwrite songs thatsoundedlike the current rock hit of the day. With Ozzy thoughhe instantly became the Randy that everyone elsegotto hear and love – the one who composed “CrazyTrain”, “Diary of a Madman” and allthose classic songs.He wasvery focused on his own styleandsound becausewith Ozzy he finally had the freedom to just be himself.
“Being a teacherhe was veryknowledgeable of musicin general so, as a musician he hada very broadvocabulary,” Rudyexpands. “He was a very well-versedandwell-rounded playerwhowas very dedicated to hiscraft. When we weretouring, unless he wassightseeing youcould pretty much guarantee he’d be playing his guitar– practicing or working on something new. He wouldalso grabthe local phone book in whatever town or city we were in and try andfind a local classical teacher. Of course, his chances of running into an excellent classical teacherin someplaces were pretty thin but at leasthe tried!”
Randy Rhoads - one of the greatest guitar players of all time. With an amazing grasp and depth of knowledge of scales and harmonic theory, Randy insisted on no compromises as he constructed his arrangements and solos - which his work clearly shows.
Randy also insisted on no compromises for his amplification ­there's no doubt in my mind that his Marshall amps and cabinets not only accompanied but assisted Randy in his climb to greatness. There's no doubt in my mind that the tonality and presence of the Randy Rhoads White Amp will help you get there too!

Whilemuch has beenwritten about Randy the musician,little has beenwritten aboutRandy the manandit would appearthat he wasequally as special as a person as he was a player. “…he inspired, cheeredandmade everyonein contactwith himfeel good.”Ozzy wrote in Tribute.
“Musically Randy touched a lot peopleandstilldoes to thisvery day,” Sarzo smiles.“I was one of the few blessed ones who got to know him as a human beingand I learned a lot from him, especially howto carry yourself in the face of becomingfamous. He really tookthat wellandnever changedas a person, becoming popular didn’t affect him whatsoever.Some people thought he was quietbutsometimes I think we confuse being quiet with being humble. He was a very humble guy witha greatsenseof humour.If you spent some time with him you were bound to see himdo somethingfunny or ridiculous just forthe sake of a goodlaugh.”
Sadly, as we allknow, Randy’s brief but brilliantcareer cameto an endon March19th, 1982, following a tragic and unnecessary planecrash. As Mrs. Rhoads pointsout, “he accomplished so muchin his short life. Only the Lord above knows how muchmore he couldhave given us.”
As already mentioned, despite his shooting-starlike life, Randy’s legend not only endures,it continues to grow. In additionto still regularlyappearing on the coversof the world’s leadingrock guitar magazines, Randy was inductedinto theworldfamous Hollywood RockWalk of fame in 2004.Tohelp celebrate this momentous occasion, Dr.Jim Marshall OBE wrotethe following in a letter to Delores: “I was andstillam delighted that he played through Marshalls and consider him to be one of the finestambassadors of my amplifiers to this very day– thefact that he is still rightfully held in such high regard by so many musicians speaks volumesregardingthe tremendousimpact he had on the worldof rockguitar.”
At the aforementioned inductionceremony – with the help of the one and only Zakk Wylde,who was also in attendanceas a speaker – the wheels started well and truly rolling towards the creation of the Limited Edition 1959RR. As Zakk toldme way backin 2001when we were working on hisown signature head,“forget about me, the guy who has to have a signature Marshall is Randy. End of story.” Weallagreed and so thankfully so did the Rhoads family. The result is the stunning looking andsounding limited edition head you are now the proudowner of.Thankyou Mr. Wylde...and thankyou Randy!!
To close, why is Randy’sinfluence still so huge a staggering 26 yearsafter he was taken fromus?Rudy Sarzo’s answeris beyond perfect: “Well, since I joined MySpace I get tons and tons of messagesfrom not onlyolderfans but from a lot of young musicians whohave been touched by his musicandhis playing. When they hear it they hearthe same purity and soulfulness that we heard when we heardRandy forthe first time. Thathasnotbeen lostor diminished bytime. Thesame exact thing applies to the music of Jimi Hendrix– it has a certain characteristic that makesit timeless. Randy hasthat same timeless quality to his sound,songwriting and playing style.”
For these verysame reasons,Marshall Amplification is proud to offer the LimitedEdition 1959RRin tributeto Randy’s timelesstalent.

Randy Rhoads? He was a total life changing experience for me. I can still remember back to when I was a 10 year old kid hearing "Crazy Train" for the first time and immediately thinking "that's all I want to do. If I could just play that whole song I'll be
happy as a guitarist!" On top of being such a phenomenal and innovative player and soloist Randy was also an amazing composer. He was definitely an epiphany in my life.

Randy was a phenomenal player and probably my first real taste of heavy guitar. Before I heard him I was listening to hard rock like Van Halen and Randy was much more classical sounding and heavier
sounding too. Both his rhythm playing and his leads were incredible. The only time I saw him play live was on New Year’s Eve the year before the tragedy occurred and he really did blow me away. Randy was a tiny dude and must’ve only weighed a 100lbs wet! His guitar was almost as big as he was but he played the hell out of it.
Kerry King, Slayer
I saw Randy Rhoads when I was 14 years old. He had the best rock sound I have EVER heard live. His tone and playing blew my mind.
Randy had a unique gift and produced many tasty riffs and melodies. He shall remain one of the greats.
Randy Rhoads is truly a guitar icon. His unique approach to songwriting, riff construction and lead playing singlehandedly established a new standard for metal guitar that would last decades beyond his all too brief career and untimely death.
Randy's style and techniques, both on stage and in the studio, are every bit as relevant today as they were in 1981, and remain THE template for heavy metal lead guitar. His influence is absolutely colossal, shaping generations of future artists. It's amazing to think that such an abbreviated catalog of material, cut short by tragedy, could so change the genre, but his impact is undeniable. Randy was my very first heavy metal guitar hero, and is a huge part of why I was drawn to music. His playing still gives me the same "goose bumps" it did when I was 14 years
old.... and for that, I remain grateful.

1. POWER SWITCH
This is the On/Offswitch formainspower to the amplifier.It willlightup when your amplifier is receiving the correctmainspower and is switched on. It willnot be lit when the amplifier is switchedoff and/oris not receiving mains power.
Note:Please ensurethe amplifier is switched off and unpluggedfrom the mains electricity supply whenever it is moved.
2. STANDBY SWITCH
The Standby Switchis usedin conjunction with the PowerSwitch (item1) to ‘warm up’ theamplifier before use and to prolong the life of the output valves.When powering up theamplifier always engage the Power Switch first, leaving the Standby switchon ‘Standby’.This allows theapplication of the voltage required to heat thevalves to their correct operating temperature.After approximatelytwo minutes the valves will have reachedthecorrect operating temperatureandthe Standby Switchcanbe engaged.In order to prolong valve life, the Standby Switch aloneshould alsobe usedto turntheamplifier on andoff duringbreaks in a performance. Also, when switching off, always disengage the Standby Switch priorto the mainPower Switch.
Note:The following fourcontrols - PRESENCE (4), BASS (5), MIDDLE (6) & TREBLE (7) - are allshared, meaning thatthey all workon bothChannel I and ChannelII.TheTreble, Middle and Bass controls are highlyinteractive and alteringone controlcanchange thewaytheother twobehave. Forthis reason, experimentation is recommended. Randy’spreferred settings areshownon the panel above.
3. PRESENCE CONTROL
This control operates in the 1959RR’s power section and addshigh frequenciesto your sound by altering the power amplifier’s negative feedback. Turningthis controlclockwise addsmore edgeand ‘sparkle’ to your sound,making it crisper and more cutting.
4. BASS CONTROL
This adjusts the bottom end,turning it clockwiseincreases the amountof low frequencies in thesound.
5. MIDDLE CONTROL
This adjusts the level of thoseall-importantmid-range frequencies. Turning it clockwise increases the mids and fattens your sound,giving it more punch. Turning it anticlockwise reduces the mids.
6. TREBLE CONTROL
This adjusts the top-end. Turning it clockwise increases theamount of high frequencies (treble)present in the sound, makingyour tone brighter.
Tone/Tech talk - The modified Valve 1 stage
Unlike a standard Marshall1959 Super Leadamplifier yourRandyRhoads modelcontains a modificationthat increasesgain and therefore extra distortion within the circuit. Thismodification ‘hotrods’ theamplifier making it easier to push it into thesaturationlevels necessaryforthesoundthat Randy needed for his musicalstation.
The change is verysimple buteffective and involves ‘cascading’ (feeding the output of the first stage intothe input of the second stage) the twohalves of valve 1. Traditionally,each halfwouldserve as input buffer/first gainstage for the two channels, i.e. one halfforchannel 1 and the other forchannel 2, fromthere they would separately feedtherespective signals to the next stagewhich would mix them, furtheramplify themand feed them to the tone stack.
Cascading valve1 resultsin the guitar signal beingincreased by around36dB or 60 times,much larger thanit wouldnormallybe at this point in the circuit. Subsequentstages then try to amplify this larger signal by similaramountsand quickly run out of headroom causing thewaveformto distortseverely. The two channel volumes still remainfunctional after the modification butadoptdifferent rolesfortheir affect on the tone, allowing control of the extragain and volume. Plugging into channel 2 routes the guitarsignal throughthewholecascade circuit whileplugging into channel 1 allowsyou to bypass thecascade andusetheamp in its standardformat where‘Volume 1’ will function as it normally would. Standard Channel 2 formatis sacrificed due to the modification.
7. VOLUME I
This controlsthe overalloutput level of Channel I, turning it clockwise increasesthe volume.This channel is voiced for a higher trebleresponse.In fullcascademode, this controls the amountof signalamplified by the second half of valve 1, thereby acting as a crudemaster volume for the whole cascade circuitandcan also be thought of as a further gain control for the boostedsignal to the subsequent stages of the preamp. In standard mode i.e. guitar plugged intochannel 1, it functions just likea normal unmodified 1959 Super Lead volume control.
8. VOLUME II
Full cascade mode. Thiscontrols the amount of signal amplified by the first half of valve 1 that is fed to the secondhalf,thereby acting as a gain control forthe cascadecircuit itself.
9. HIGH SENSITIVITY INPUT FOR CHANNEL I
This is the ‘highsensitivity’guitar inputforChannel I - the brighter of the two channels- and is the most commonly usedinput on standard unmodified models. Always use a high quality screenedguitar lead. NOTE- Plugging intothis input bypasses the cascade and theampfunctions in standard format.
10. LOW SENSITIVITY INPUT FOR CHANNEL I
This is the ‘low sensitivity’ guitarinputfor Channel I. It is 6dB lower (half)than the ‘high sensitivity’inputand results in lessgaincapability which may be required for guitarswith very hot outputpickupsoractive circuitry onboard. NOTE - Plugging into this input also bypassesthecascadeand the amp functionsin standard format.
11. HIGH SENSITIVITY INPUT FOR CHANNEL II
Plugging into thisinputenables the full cascade.
12. LOW SENSITIVITY INPUT FOR CHANNEL II
Plugging into thisinputenables the full cascade. It is 6dB lower (half) than the ‘highsensitivity’input andresults in lessgain capability which may be required for guitars with very hotoutput pickupsor active circuitry onboard.
