From the Chairman
I would like to personally thank you for selecting one
of my vintage re-issue amplifiers.
The Marshall reputation has been built upon many
things, but our longevity comes mainly as a result of
the continual relevance of the concepts behind the
design and build of our amplifiers. Added to this are
solid workmanship, reliability, stylish looks, and above
all – great tone. The continual fascination and love that
many guitarists show for our vintage amplification is a
testament to just how relevant and important these
models still are today.
The amp you have just acquired was originally
launched in the 1960s. A time when the face and
sound of popular music was rapidly changing and
players were constantly pushing back the musical
boundaries. Each of these amps was there at the
beginning of this music revolution and all played their
part. From Pete Townshend, Eric Clapton and Jimi
Hendrix, to Jeff Beck and Paul Kossoff, the list of great
‘tone’ players who pioneered the use of the natural
distortion from these amps, reads like a who’s who of
guitar players.
Our re-issues of these models are as faithful as
possible to the originals in terms of looks and tone.
Hand-crafted in the UK these superb units feature
finger-jointed cabinets of birch plywood, hand-welded
chassis’s, hand-wired potentiometers and valve bases
and the highest quality PCBs and componentry.
I would like to wish you every success with your new
amplifier and welcome you to the family of great
players who use the classic Marshall tone.

Introduction
The Marshall re-issue range consists of the 100 Watt 1959SLP head, the 50 Watt 1987X head,
the 2245 ‘JTM45’ head and 1962 ‘Bluesbreaker’ combo. All are faithful reproductions of the
originals, which shaped the sound of the electric guitar as we know it.
The main characteristic that these amps share is their simplicity of operation and superb natural
valve tone. Achieving the beautifully organic and vibrant overdrive which is their trademark, can
only be done in one way – crank’em up! The result is pure, majestic tone uncluttered by
unnecessary circuitry. With solos this produces a big, round, warm sustain, full of classic
character. With chord work you get a bark and percussive attack with a natural sounding break up,
which allows each note to ring out in a glorious musical crunch.
FX Loop
Due to high demand, a sonically transparent effects loop has been added to the 1959SLP and
1987X models. This circuitry has been designed to not colour the guitar sound, so that your tone
remains pure. The bypass switch gives you the option of completely removing this circuitry if
desired. The effects loop level selector ensures compatibility with rack processors or floor pedals
(stomp boxes).
Page 4
1. Level
Provides two different loop levels to suit the type of
effects connected to the series effects loop. The
higher level (+4dBV) suits rack processors and the
lower level (-10dBV) suits floor pedals.
2. Bypass
This switch completely bypasses the circuitry
involved in the effects loop to maintain absolute tonal
integrity.
3/4. Effects Loop
To increase the flexibility of your amplifier further
you may choose to add external effects. The Effects
Loop allows direct connection of either floor pedals or
rack processors, with the level control (item 1)
providing the correct operating level.
Usually effects involving distortion or Wah Wah
would not go through the loop, but between the guitar
and amp input. Time or modulation based effects
such as Chorus, Delay and Reverb are best suited to
the loop.
The signal is sent out from the amplifier to the input
of your effects processor/pedal from socket 4 (Effects
Send) then from the output of the processor/pedal is
returned into the amp via socket 3 (Effects Return).
5/6. Loudspeaker Outputs
These are for connection to an external load, i.e.
speaker cabinet(s). (See item 7).
Please refer to Important Safety Instructions, page 2.
7. Output Selector
Matches the amplifier’s output to the load
impedance.
With all-valve amplifiers it is imperative that the amp
is connected to a load whilst in operation and that the
impedance selected on the amplifier matches the total
impedance of the speaker cabinet(s) being used. For
example, if the amp is running into a single 16 Ohm
cab, the amp should accordingly be set to 16 Ohms.
If running into two 16 Ohm cabs, the amp should be
set to 8 Ohms. If running into two 8 Ohm cabs, the
amp should be set to 4 Ohms.
Failure to comply with these points will result in
damage to the amplifier.
Your amp should be completely powered down
before the selector is turned.
8. Mains Selector
Matches the amplifier mains transformer voltage to
the incoming mains voltage. Ensure that the rotary
Mains Selector is set to the correct mains voltage
applicable to the country where used. If you do not
know the mains input voltage contact your authorised
Marshall dealer.
Your amp should be completely powered down
before the selector is turned. Adjustment from
230/220V to 110V or vice versa will require the mains
fuse to be changed to the corresponding value as
detailed on the rear panel.
9. Mains Input
Your amp is provided with a detachable mains
(power) lead which is connected here. The specific
mains input voltage rating that your amplifier has
been built for is shown on the back panel. Before
connecting for the first time, please ensure that your
amplifier is compatible with your electricity supply. If
you have any doubt, please get advice from a
qualified person. Your Marshall dealer will help in this
respect.
10. Mains Fuse
The correct value of mains fuse is specified on the
rear panel of the amplifier. Please refer to Important
Safety Instructions, page 2.
11. H.T. Fuse
The correct value of H.T. fuse is specified on the
rear panel of the amplifier. Please refer to Important
Safety Instructions, page 2.

1. Power Switch
On / Off Switch for mains power to the amplifier.
Please ensure the amplifier is switched off and
unplugged from the mains electricity supply before
being moved.
2. Standby Switch
The Standby Switch is used in conjunction with the
Power Switch (item 1) to ‘warm up’ the amplifier
before use and to prolong the life of the output valves.
When powering up the amplifier always engage the
Power Switch (item 1) first. This allows the
application of the voltage required to heat the valves
to their correct operating temperature. After about 2
minutes, when the valves are up to the correct
temperature, the Standby Switch can be engaged.
Upon doing this the H.T. (High Tension) which is the
high voltage required by the output valves to pass
signal (and hence produce sound) is applied.
To prolong valve life, the Standby Switch alone
should be used to turn the amplifier on and off during
breaks in a performance. Also, upon full power down,
always disengage the Standby Switch prior to the
main Power Switch (item 1).
3. Indicator
The Indicator will be lit when your amplifier is on
and will not be lit when the amplifier is switched off.
4. Presence Control
Adds higher frequencies to the guitar tone, creating
crispness and bite. Turning this up will make the
sound more cutting and ‘present’.
5. Bass Control
Controls the amount of low frequencies or bottom
end in your tone.
6. Middle Control
Dictates the middle register of the amplifier.
Turning this up will make your guitar sound fatter.
Conversely reducing the amount of middle in your
tone will result in a sharper and thinner guitar sound
for a more ‘scooped’ tone.
7. Treble Control
Controls the high frequencies of the guitar tone,
making your guitar sound brighter when increased.
(Note: The tone network is highly interactive and
altering one control can change the shape of the
sound in relation to the other tone controls.
Experimentation is the best way to achieve your
desired sounds.)
8. High Treble Loudness 1
Controls the overall output level of Channel 1.
Note: This channel is voiced for a higher treble
response than Channel 2.
9. Normal Loudness 2
Controls the overall output level of Channel 2.
Note: Channel 2 is voiced for normal response.
10. Input Jack
Connects the guitar to Channel 1.
Note: Though the first input of the first channel is
the input that most guitarists use, don’t be afraid to
experiment. Some guitar players prefer to mix the two
channels together by connecting a short, screened
patch lead between the second input of Channel 1 and
the first input of Channel 2. If you then plug your
guitar into the first input of
Channel 1 (item 10), you can mix
the different tonal characters of
each channel for greater
flexibility. (See diagram).
11. Input Jack
Connects the guitar to the lower sensitivity input on
Channel 1.
12. Input Jack
Connects the guitar to Channel 2.
13. Input Jack

8 Ohms, therefore the output selector should be set to
8 Ohms.
If an additional 8 Ohm extension speaker cabinet is
used in conjunction with the internal speakers the
output selector should be set to 4 Ohms.
Note: No additional extension speaker cabinet with
an impedance lower than 8 Ohms should be used in
