HOW THE ELECTRONICS WORK ON YOUR GIBSON GUITAR
Your Gibson Electric Guitar is capable of producing a variety of sounds
by manipulating the controls.
Tone Controls
The tone controls on all models are "treble cut" controls. This means
that as you turn the knob counterclockwise you reduce the treble output
of that pickup and produce a darker tone. Turning the knob fully
clockwise will produce the brightest sound. T his means that the pickups
full range of harmonic frequencies are being passed on to the amplifier.
Selector Switch
The selector switch permits you to turn pickups on and off. In the
middle position both pickups are turned on. When the switch is "up" the
neck (or Rhythm) pickup only is turned on. When the switch is "down" the
bridge (or Treble) pickup is turned on.
Coil Tap Switch (certain models)
Certain models are equipped with a coil tap switch. This allows a
double-coil (humbucker) pickup to give you the sound of a single-coil
pickup.
When the switch is "up" you have the traditional humbucker sound. When
the switch is "down" it produces the brighter sound that you expect from
a single coil pickup. Some volume loss is experienced in the single-coil
mode.
The Varitone Control (certain models)
This control works through a reduction of the fundamental harmonic
frequencies. The higher the setting, the greater the loss of "low"
frequencies. Positions 3 and 4 produce a sound similar to a single-coil
pickup. The exact frequency "cuts" are listed below:
Position 1--> no cut
Position 2--> -5db at 1950hz
Position 3--> -12db at 1 100hz
Position 4--> -16db at 620hz
Position 5--> -18.5db at 360hz
Position 6--> -21db at 1 20hz
