A BRIEF HISTORY OF GIBSON ELECTRIC GUITARS

Gibson’s legendary acoustic engineer, Lloyd Loar, was experimenting with electric instruments in 1924, at the dawn of electronic amplification. However, Gibson’s struggle to dominate the banjo market took precedence through the 1920s, and it wasn’t until the mid-1930s that the company once again turned its attention to electric guitars. In 1935 Gibson’s Walt Fuller designed a pickup that was introduced on the E-150, an aluminum-body lap steel. Early in 1936, the pickup was put in a midline archtop model and named the ES-150—ES for Electric Spanish, 150 for the retail price of $150 for the guitar and amplifier set.

The original ES-150 bar pickup with its hexagonal housing is now known as the “Charlie Christian” pickup, because it was installed on the ES-150s and ES-250s that Christian used to establish the new concept of electric jazz guitar.

Gibson made several improvements in pickup design before World War II, although many players still consider the “Christian” pickup to be the best jazz pickup ever made. Immediately after World War II, Gibson introduced the P-90 single-coil, with six adjustable polepieces and a black plastic cover, usually with “dog-ear” mounting extensions. The P-90 is still in production and still sets the industry standard for a single-coil pickup.

The first postwar Gibson electrics followed the prewar concept of an electric guitar as a conventional acoustic archtop with a pickup installed on the top. Gibson added a second pickup to the ES-300 in 1948 and then became the first company to offer a three-pickup model with the introduction of the ES-5 in 1949.

Although the advantages of a solidbody guitar had been known to Hawaiian steel guitarists for almost 20 years, it took the persuasive powers of Les Paul, the world’s most famous guitarist in the early 1950s, to convince Gibson to make a “Spanish style” solidbody. Gibson designed the new model with a carved top, not only to give it the look of a traditional archtop—a style invented by Gibson—but also to make it difficult for other makers to copy. Les, who had been playing a homemade solidbody guitar, nicknamed The Log, since 1941, specified a maple top cap to increase sustain, coupled with a mahogany back to lighten the weight. Les also specified the famous “Goldtop” finish.

The Les Paul Model debuted in 1952. The bridge and tailpiece were upgraded when Gibson introduced the patented tune-o-matic bridge in 1954, and the original single-coil pickups were upgraded with the introduction of Gibson’s patented humbuckers in 1957. Otherwise, the original Les Paul is essentially the same guitar today as it was when it was introduced.

In 1954 the growing popularity of the Les Paul Model prompted Gibson to expand the line. On the high end, the Les Paul Custom sported an Ebony finish and low frets for fast action, and it immediately gained two nicknames: the Black Beauty and the Fretless Wonder. On the more affordable end, the Les Paul Jr. featured a flat “slab” top and a single pickup, and it became the best-selling Les Paul of the 1950s.

One year after the Les Paul Jr., Gibson offered a two-pickup version of the slab-body model called the Les Paul Special. The Special was further distinguished by its yellow-stained “TV” finish.

The double-coil humbucking pickup, invented by Gibson engineer Seth Lover, debuted in 1957 on the Standard and Custom, introducing the sound that would shape rock 'n' roll music in the 1960s.

In 1958, Gibson introduced more important design innovations than in any other year in the company’s history. Gibson president Ted McCarty combined the look of an ƒ-hole archtop with the performance of a solidbody and came up with a completely new type of guitar—the semi-hollowbody ES-335. McCarty also designed two radically modern solidbody shapes: the Flying V and Explorer.

The body of the Les Paul Jr. received a pair of rounded horns to become Gibson’s first doublecutaway solidbody. And the finish color on the Les Paul Model was changed to Cherry Sunburst, which let the grain of the maple top show through. The model name was changed to Les Paul Standard, and the sunburst Standards from 1958-60 would become some of the most valuable collectibles in the guitar world. All of this happened in 1958.

The new Les Paul Jr. set in motion a complete redesign of the Les Paul line. In 1959 the Special went to the rounded-horn double-cutaway shape and was renamed the SG Special (SG for Solid Guitar). In 1960, all four models were revamped and given a new “SG” body shape, featuring a thinner, double-cutaway body with pointed horns. The Custom, Standard, and Jr. retained the Les Paul designation through 1962, after which they became SG models.

Gibson’s design innovation continued into the 1960s when Ted McCarty hired legendary automotive designer Ray Deitrich to design a Gibson. The result was the Firebird series, and the companion Thunderbird bass series of 1963. The Firebirds “reversed” conventional designs, with their elongated treble-side horn and treble-side tuners. They also introduced neckthrough-body construction and smaller “mini-humbucking” pickups to the Gibson line.

11

12

In response to the rising demand for 1950s-style Les Pauls, the carved-top models were reintroduced in 1968. A new model, the Les Paul Deluxe, featuring mini-humbucking pickups appeared in 1969. The Special was revived in the 1970s and the Jr. reappeared in the 1980s. The Flying V, Explorer, and Firebird were also brought back into regular production, as musical styles began to catch up with these ahead-of-their-time designs.

While the original four Les Paul models continued as the foundation of the line, Gibson offered new variations, such as the Studio, Classic, and Double-Cut Standard, in order to give musicians all the features they wanted in a Les Paul guitar. In the 50-plus years of the Les Paul, Gibson has offered more than 100 different variations. In 2003 Gibson honored Les Paul for his achievements as a performer, recording innovator, and guitar designer by presenting him with a special Artist for Eternity Award.

As Gibson celebrated the 50th anniversary of the Les Paul in 2002, the company rocked the guitar world once again by introducing the first digital electric guitar. It represents the biggest advance in electric guitar design since the instrument was invented, and moreover, it serves notice that Gibson electric guitars will continue to epitomize the highest levels of Quality, Prestige and Innovation.

DESIGN AND CONSTRUCTION

Body. The solidbody guitar was invented to increase sustain, produce a brilliant tone, and

eliminate feedback caused by a vibrating top. These qualities are enhanced by wood with high density, such as maple. Les Paul would have preferred for his model to have had a solid maple body, but density translates to weight, and a solid maple Les Paul Model would have been exceedingly heavy. A compromise was reached, with lighter-weight mahogany used for the main part of the body and maple for the top cap. Most of the carved-top Les Pauls have the combination maple/mahogany body, while the “slab” or flat top models have a solid mahogany body. Flying V’s, Explorers, and Firebirds have a solid mahogany body.

Neck and Headstock.

Gibson USA models are constructed of a single piece of mahogany. The Firebird or Thunderbird IV bass neck is made of nine-ply mahogany and walnut (or all mahogany laminates), and it extends completely through the body. Fingerboards are of ebony or rosewood.

Mahogany is a time-proven material for guitar necks, and the necks of most

characteristics of each model. Neck profiles can be “rounded ’50s” or “slim ’60s” (or a slight V-shape available only on the BluesHawk). Scale length (string length) is 24 3/4" on the Les Paul, X-Factor and SG models, 25 1/2" on the Chet Atkins, Americana, and Hawk models and 34" on basses.

Pickups.

pickups, which were designed to do what their name says: “buck” the hum caused by fluorescent lights, rheostats, and other electrical interference. They accomplish this with two coils of wire, wound in opposite directions so that they cancel out interference. Also, they produce a powerful sound that is the foundation of rock 'n' roll music.

Gibson produces humbuckers in a variety of subtle variations, achieved by the use of different magnets and different combinations of winding turns. In addition, some Les Pauls have humbuckers without the metal cover pieces, which results in a hotter signal. For individual model and pickup specs, please refer to Gibson’s website, www.gibson.com.

When the P-90 was introduced in 1946, it was the most powerful pickup of its kind. And it still is. Among the many examples of the P-90 sound are Carlos Santana’s Les Paul Special on Santana’s classic recordings, Leslie West’s Les Paul Jr. with the group Mountain, and the Who’s Pete Townshend with an SG Special on

factory, they can be adjusted. The height of the pickup can be adjusted by the two screws found at either end of the pickup, in the mounting ring. Individual string volume can be adjusted by turning the polepiece screws. Bringing the pickup or pole screw closer to the strings makes the signal stronger or “hotter.”

Volume controls:

The volume knob nearest the bridge controls the “front” or neck pickup; the knob nearest the edge of the guitar controls the “back” or bridge pickup.

Tone controls:

knob nearest the bridge controls the “front” or neck pickup; the knob nearest the edge of the guitar controls the “back” or bridge pickup.

The tone controls are the “treble roll off” or “cut” variety. The tonal quality of the instrument is darkened by the reduction of treble rather than the addition of bass. The tone control turned all the way counterclockwise results in maximum reduction of treble and produces the “darkest” sound. The tone control turned clockwise to its maximum position allows the pickup’s full harmonic frequencies to pass through, producing the guitar’s brightest sound.

Pickup selector switch:

the “front” or neck pickup. The down position selects only the “back” or bridge pickup. The middle position engages both pickups. The tone and volume controls will only be active when the corresponding pickup is selected. On models with three pickups, the selector switch activates the front pickup (front position), the middle and back pickup together (middle position), and the back pickup (back position).

and individual string length. Height is adjustable up and down by means of thumb wheels under the bridge at either end. Each string saddle is adjustable forward and back with a small standard screwdriver. Action adjustment (up and down) is set at the factory to the correct height for playing comfort and for buzz-free action. Raising the bridge will result in stiffer action; lowering the bridge will result in faster action but may also result in fret buzz. Climatic or humidity changes, or changes in string gauge, may necessitate a bridge adjustment.

Any change—in bridge height, string gauge, or climate—can affect the intonation and cause a guitar to play out of tune in some fret positions. When this happens, the string length needs to be adjusted, and this is accomplished by moving the individual saddles forward (toward the neck) or backward (toward the tailpiece). The screw heads are on the pickup side of the bridge, although there are many Gibsons that have the screw heads facing the tailpiece. To check intonation, compare the pitch of a string that is fretted at the 12th fret against the harmonic at the 12th fret (accomplished by touching the string lightly with the left hand, without pressing it all the way to the fret). If the fretted note is higher than the harmonic, the string should be lengthened by moving the saddle toward the tailpiece until the two notes are the same. If the fretted note is lower than the harmonic, the string length should be decreased.

The Tune-o-matic bridge allows for adjustment in overall bridge height

The tune-o-matic bridge was designed to adjust for string changes (gauge or type) and other physical changes but not for problems with intonation due to string wear. Should a string lose its intonation due to wear, we strongly recommend changing the string and not the bridge setting.

CARE AND MAINTENANCE

Finish.

A Gibson instrument always attracts attention, whether it is on a concert stage before thousands or on a guitar stand in a home studio. After the classic body lines of a Gibson, the finish makes the strongest impression.

Perspiration acids, heavy fingerprinting, dust, and grime from on-the-job usage are unavoidable. However, a minute or two spent with Gibson’s instrument care products—guitar polish, fretboard conditioners, string cleaner/lubricant, and polishing cloth—will restore a finish to like-new condition.

Gibson’s nitrocellulose lacquer finish not only looks great, it is also easily repairable—by a professional. Minor scratches and dings can be fixed without completely refinishing the instrument.

if you take care of it. In determining whether conditions might be harmful to your guitar, the rule of thumb is, if you are comfortable, then your guitar will be comfortable. Here are some conditions to avoid.

Your Gibson is a durable instrument. It is likely to outlive you—

Heat and cold:

peratures and humidities—but not to sudden changes in temperature or humidity. Just as a hot drink will crack a chilled glass, the finish of a Les Paul will crack if a guitar that has been sitting in the trunk of a car in wintertime is suddenly exposed to the warm air of a heated room. In these conditions, let the guitar warm up gradually inside the case before opening the case.

Rain:

Water wipes off the instrument’s finish easily, but if allowed to remain, it can cause ugly

water spots in the lacquer.

Sun:

Avoid direct rays of the sun on your Gibson. Direct sunlight can blister or discolor the finish.

More Things to Avoid.

contact points and strap fasteners are secure.

Guitar stands with rubber supports that contain dye or plasticizers can “eat away” at the lacquer finish or leave a stain on your guitar that goes through the lacquer finish and into the wood. These stains are permanent and this sort of damage is ty. We recommend covering the rubber parts of the stand with a soft cotton cloth (such as a guitar polishing cloth) and using a guitar stand only for temporary “storage” of your instrument.

Avoid sharp blows to any part of your instrument. Be particularly alert to possible blows to the back of the headstock, machine heads (tuners), and in the neck heel area. Many headstock breaks are the result of a guitar being knocked over or dropped while it’s still in the case, so do not stand the case on its end.

Should major adjustments become necessary, contact your local authorized Gibson dealer or service center.

Strings.

Fresh strings are a vital part of that “new instrument” sound. When strings begin to go dead, a guitar loses its edge, and as the strings undergo further wear and tear they go “dead.” Your Gibson will sound its best with new strings.

21

How often should you change strings?

hard you play, and also on your individual body chemistry. Some professional musicians change strings before every show in order to maintain the brightest edge on their sound. More casual players may only need to change strings every month or two. For some players, even light perspiration shortens the life of their strings. The sound of the strings is the only sure way to judge whether or not they need to be changed. And if one string needs to be changed, the others can’t be far behind. To maintain tonal balance, change the whole set.

That depends on how much you play your guitar, how

22

When changing strings, we recommend changing one string at a time in order to maintain tension on the neck and bridge. The pressure of the strings holds the bridge and saddles in place, and removing all the strings could necessitate a new setup.

Use high quality strings.

formance of your strings is to use high quality strings. Your Gibson comes from the factory with a set of strings made by Gibson and designed exclusively for Gibsons. Although the string set from the Gibson factory is suitable for virtually any style of music, Gibson offers a variety of string styles and gauges for specialized purposes.

to constantly go out of tune. To correctly install strings:

1. Be certain the first winding of the string around the machine head stem (tuner

post) goes over the exposed tip of the new string. The rest of the winding should then go under the exposed tip of the new string. When pressure is applied by tightening the string to pitch, a clamping action keeps the string from slipping around the machine head stem.

The most obvious action you can take to maximize the life and per-

Improperly installed strings can slip, which will cause your Gibson

2. Be certain the string is wrapped around the tuner post an adequate

number of times. For unwound strings, at least five turns around the machine head stem are necessary. For wound strings, two or three turns are adequate.

What gauge strings should be used?

means the high-E string is .010 inches in diameter. The low-E is .046 inches in diameter. The set is designed so that all strings are in proportion to one another, ensuring that the action and the volume will be consistent across the entire fingerboard. Gibson offers “9s,” “11s,” and a variety of other gauges and compositions, all of which are balanced for consistent tension.

What brand of strings should be used?

and Gibson has more experience than any other string maker when it comes to matching strings to Gibson guitars. Gibson strings are manufactured to exacting standards to achieve the highest level of quality and performance.

NEW TECHNOLOGY - THE GIBSON ROBOT GUITAR

The Impossible is Now Possible.

Introducing the Gibson Robot Guitar, the world’s first guitar with robot technology.

Gibson’s Robot Guitar is the only guitar available with the auto-tuning system described herein as original equipment.

Your Gibson Robot Guitar will be pre-calibrated for a standard .010-.046 set of strings. If you change string gauges, restore factory defaults, or are installing the system yourself, you may first want to calibrate the Powerheads individually using the calibration method as described in the Setup Mode section of this guide. However, since each Powerhead is selfregulated with a Dynamic Runtime Algorithm (DRA) which ensures the change of runtimes according to each string, after several tunings the system will perfect itself automatically.

A special “eFunction” algorithm is provided by the software to assist the tuning process. We recommend using it in the “enabled” mode.

This Owner’s Manual is intended to provide a working understanding of the Robot Guitar’s features to bring you the greatest benefits as you explore the exciting possibilities it has to offer. For questions or more in-depth technical information, feel free to contact us at 1-800-4GIBSON.

THE MASTER CONTROL KNOB (MCK)

The Master Control Knob not only serves as the master control for all aspects of this amazing, self-tuning system, but it will communicate with you as you learn its “language.” The MCK is quite powerful and has many uses, and we believe you will find that MCK functions will become second nature to you once you have tried them a few times.

Caution: Do not attempt to manually turn the Powerheads unless they are pulled away from the peghead so they are in the disengaged position! Otherwise the Powerheads can be damaged.

BASIC OPERATIONS

The Robot Guitar’s Master-Control Knob (MCK) is what is commonly referred to as a “push-pull” knob. When in the normal position, it behaves as a regular volume or tone pot, depending on which series you have. When the MCK is pulled out, the system is activated.

When the system becomes active by pulling out the MCK, it immediately places your instrument in ‘Standard Tuning Mode’ at A440 (unless you have changed tuning defaults, see page 46), but six factory presets have been provided for your use. Each preset can be changed to your liking, but you can always restore the factory defaults as later described in this Owner’s Manual.

25

26

The MCK’s LED display will show various symbols and colors and these will be explained in the various modes of operation available to you. During the tuning process, they will behave as follows:

String LEDs Display Actions During Tuning Operations:

string not tuned = solid red measuring frequency = red flashing Powerheads turning = yellow flashing signal clipping = solid blue string frequency at extreme range = solid purple individual string in tune = solid green all strings in tune = all LEDs flash blue 3 times

During the tuning process, the guitar will be nearly 100 percent muted. After the MCK is pushed back in, full volume returns.

PRECAUTIONS:

• Never try to manually turn the tuning pegs on the Powerheads unless they are in the

disengaged position (pulled out and away from the peghead).

• Do not attempt to open the cover of the peghead electronics, the Powerheads, or the

body CPU as this will void your warranty.

• Do not ‘fret’ a string while attempting to tune the Robot Guitar. Strings must be ‘open’

for the system to function properly unless you are performing the intonation routine.

• It does not require much force to detect pitch and to tune each desired

string accurately and quickly. Strumming the strings gently will provide best results.

Powerheads will begin to unwind all strings. When they stop turning, unscrew each post’s locking nut so that you are able to remove old strings.

36

TO RESTRING YOUR ROBOT GUITAR

First ensure that all Powerheads are disengaged by pulling the pegs away from the peghead. This is very important! Turn each peg so that the post-hole is roughly in line with each corresponding string as it leaves the nut of your guitar.

Guide each string through your tailpiece, over the saddle (where contact is essential), through the nut slot and then the post-hole as you would with any other guitar, but place a slight amount of tension by hand before screwing each locking nut down tight. Cut the loose end of each string close to the post so that they will not make contact with other strings, as that would cause your system to function improperly.

Now you are ready to engage String Up Mode. MCK should be on the green revolving arrow as described on the previous page. After the display is pressed for 3 seconds, all strings will wind themselves close to their correct pitches, whereupon you must fine tune your guitar using Normal Tuning Mode. (When all strings are removed, don’t allow the tailpiece to move or

it could damage its connector!)

TO ACTIVATE STRING UP MODE FOR A SINGLE STRING

(as in the case of replacing a string broken while playing)

Install the string in the manner described above (remember saddle contact is crucial!). Simply select the LED for the string you are replacing, turn to the green revolving arrow and toggle it from green to red and back to green. Press the display for three seconds. The Powerhead of the selected string will begin winding close to normal tuning, and when it stops, you will be ready to fine tune it using Normal Tuning Mode.

Speed / Accuracy Settings

MCK Position

Enter Setup Mode and turn to A LED

Pegs shines white, A shines blue

#

Press display once. Current Speed / Accuracy setting will be indicated by flashing green LEDs (as described below)

The Powertune system is adjustable to a pitch accuracy of .2 Cent. However, this will cause tuning functions to take slightly longer, and in live applications a relaxed accuracy is advisable. There are 6 levels of setting. The factory preset setting will show 4 green flashing LEDs, indicating that you are using an accuracy setting of approx. 1 Cent, which is practical for most applications. Relaxing this setting will cause the overall tuning process to run at a faster rate, and this can be useful in live applications. In the studio, you would want the maximum accuracy measurable. In this case, range will be changed and adjusted by rotating the MCK. The high end of accuracy (.2 Cent) is indicated by 6 green LEDs. The low end (i.e., fastest speed) is indicated by one green LED. Even at the low end, accuracy of tuning is still

2.5 Cent! To store your chosen setting, press display once. You will leave Setup Mode automatically.

CALIBRATING POWERHEADS

The Robot Guitar will be pre-calibrated for a standard .010-.046 set of strings. If you change

string gauges, restore factory defaults, or are installing the system yourself, you may first want to calibrate the Powerheads individually using the Motor Calibration Mode as described below. Remember though, each Powerhead is self-regulated with a Dynamic Runtime Algorithm that ensures the change of runtimes according to each string. After several tunings the system will perfect itself automatically.

MANUAL CALIBRATION OF POWERHEADS

Enter Setup Mode and turn to LED I, press display. The Peg and I LEDs will shine white.

Now you are ready to calibrate any or all of your Powerheads.

First, turn the MCK to the Powerhead you want to calibrate (selected strings are indicated by solid blue) and press the display once. Strum the string and it will begin to alternate between flashing red and green. Pause a few seconds and strum it again. Repeat this simple procedure while the Powerhead adjusts itself. When the LED for that string changes to the next string in order, you know that the Powerhead you selected first is done. It’s that simple.

CHARGING AND BATTERY INFORMATION

The Robot Guitar comes with a battery pack containing two rechargeable batteries.

A special charger is also included with the system.

The battery charge level is indicated each time you activate your system, as indicated below. You may expect more than 200 tunings between charges. There is no need to open your guitar to access any of the battery charging functions. When the system is enabled but inactive for more than one minute, the battery will switch off automatically. A special protection mode is built into the charging system, so always begin the charging process by connecting your guitar cord to the charger last. Short patch cords are most effective during charging.

BATTERY LEVEL

Each time the MCK is first activated, it will indicate if charging is needed immediately by

showing the battery symbol flashing red.

Function MCK Position Display LEDs Action Remarks

51

Charge Mode

Pull MCK out, turn to C LED and press display

Your current charge level will be displayed for about 3 seconds. The level of charge will be indicated by how many green LEDs you see (betweeen 1 and 10).

Now you will see a flashing red battery symbol on the MCK, indicating your system is looking for its charger. Plug in the AC power plug of your charging unit and the charger will flash red, too. Connect the charging unit to the guitar with a standard guitar cord, and when the system begins to charge, the charging unit will flash green, and a running display of green LEDs on the MCK will indicate charge level. The charging unit’s LED will flash green, too.

For optimum performance, you will want a charge level of 8-10 green flashing LEDs. A fully charged battery pack will show a solid blue light on the charging unit and the MCK’s display will switch off automatically. Push MCK back to its normal position when charging is complete. A full charge should take no more than 90 minutes.

52

EMERGENCY CHARGE MODE

The system now has an Emergency Charge Mode (ECM) if its internal rechargeable battery goes completely dead or too low in charge to run the normal Charge Function. Put MCK in the C position. Plug your patch cable into the charging device and connect and plug in the transformer. The charger will blink with a red LED (seeking a Guitar). When the LED begins to blink yellow the charger can be connected to the guitar. The charger will provide enough charge to make it possible to start the regular charging mode. The condition of time to reanimate the charging mode is related to the state of battery-level (approximately 10 seconds up to a couple of minutes). After ECM is completed, the system runs in normal charge mode.

AUTOMATIC SWITCH OFF MODE

If the MCK is left in the ‘on’ position for more than 120 seconds, the system enters Switch Off Mode, indicated by a flashing green light. After 30 minutes the system turns into Standby Mode, indicated by a very slow flashing yellow light. You can re-activate the system in either status by turning the MCK.

Note: It is recommended not to store the guitar with the MCK out, as this will fully drain the battery eventually and Emergency Charge Mode must be employed.

SHORT CIRCUIT WARNING

In the event of a short circuit from negative to ground (Strings E or A to D or G) the white peg symbol will flash. This can be caused if strings are not trimmed properly at the headstock.If the short circuit runs from B or hi E to D, A or low E, the peg will flash yellow. Check to make sure no strings touch one another.
