1: INPUT: Connect your guitar here by means of
a shielded instrument cable.
OVERDRIVE CHANNEL: A high gain channel
giving you sounds from a slight edge to serious
overdrive.
2: GAIN 1: Gain 1 is active only when the Gain
Select switch (#5) is out. When active, this control adjusts the amount of compression and distortion from the amplifier. At far left, the sound
will have a thick compressed quality . As you turn
the control to the right the amount of distortion
increases. Gain 1 produces less intense distortion than Gain 2.
3: GAIN 2: Gain 2 is active only when the Gain
Select switch (#5) is depressed. When active,
this control adjusts the amount of compression
and distortion from the amplifier. At far left, the
sound will have a thick compressed quality. As
you turn the control to the right the amount of
distortion increases. Gain 2 produces more
intense distortion than Gain 1 .
4: SHAPE: Working in conjunction with the Gain
2 control, rotate the Shape control until you find
the sound you’re looking for. Rotating the control
counter-clockwise enhances the mid frequencies; rotating it clockwise enhances the low and
high frequencies. (This control is only effective
when Gain 2 is selected.)
5: GAIN SELECT: Use this switch to select Gain
1 (switch out) or Gain 2 (switch depressed). A
footswitch (#21) overrides this switch.
6: LOW: Use this control to adjust the low frequency output level of the Overdrive channel.
This control provides a range of 11dB at 80Hz.
7: HIGH: Use this control to adjust the high frequency output level of the Overdrive channel.
This control provides a range of 10dB at 10kHz.
8: LEVEL: Use this control to adjust the output
level of the Overdrive Channel. Use this control
along with the Gain and Shape controls (#2, 3 &
4) to create a wide variety of sounds.
9: CHANNEL SELECT: Use this switch to select
the Clean channel (switch out) or the Overdrive
channel (switch depressed). One of the triangular LEDs beside the switch will illuminate to indicated which channel is selected. A footswitch
(#21) overrides this switch.
CLEAN CHANNEL: A normal gain channel
designed to give you crystal clear sounds.
10: LEVEL: Use this control to adjust the output
level of the Clean Channel.
11: LOW: Use this control to adjust the low frequency output level of the Clean channel. This
control provides a range of 22dB at 80Hz.
12: MID: Use this control to adjust the mid frequency output level of the Clean channel. This
control provides a range of 14dB at 600Hz.
13: HIGH: Use this control to adjust the high frequency output level of the Clean channel. This
control provides a range of 28dB at 10kHz.
14: REVERB LEVEL: Use this control to adjust
the amount of reverberation. In the full counterclockwise position the output signal is “dry” (no
reverb); rotating the control clockwise increases
the amount of reverb. The reverb can be turned
on and off by means of a footswitch (see #22).
15: INSERT: Use this jack to connect an external effects device to the amplifier. Use a stereo
1/4” male Y -cord: ring = send, tip = return, sleeve
= ground. See the illustration on the panel to the
right for more information.
16: EXT. SPEAKER: Use this jack to connect an
extension speaker cabinet to the amplifier. This
jack is wired in series with the internal speaker(s)
GX-65 Amplifier
