FRONT PANEL:

1: INPUT: Connect your guitar here using a shielded
instrument cable.
OVERDRIVE CHANNEL: A high gain channel giving you
sounds from a slight edge to serious overdrive.
2: GAIN 1: When active, sets 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 pro-
duces less intense distortion than Gain 2 and is active only
when the Gain Select switch (#5) is out.
3: GAIN 2: When active, sets 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 pro-
duces more intense distortion than Gain 1 and is active
only when the Gain Select switch (#5) is in.
4: SHAPE: Working in conjunction with the Gain 2 control,
rotate the Shape control until you find the sound you're
looking for. Turning the control towards the left enhances
the mid frequencies; turning it to the right enhances the low
and high frequencies. (Only affects Gain 2 when active.)
5: GAIN SELECT: Switches between Gain 1 (out) and
Gain 2 (in). A footswitch (see #30, rear panel) overrides
this switch.
6: LOW: Adjusts the low frequency output level: to the left
reduces the low frequency output; to the right increases it.
This control allows a range of 10dB at 80Hz.
7: HIGH: Adjusts the high frequency output level: to the left
reduces the high frequency output, to the right increases it.
This control allows a range of 10dB at 7kHz.
8: LEVEL: Sets the output volume level from the Overdrive
Channel: in the far-left position there is no output; turning
the control to the right increases the output. Use this con-
trol along with the Gain and Shape controls (#2, 3 & 4) to
create a wide variety of sounds.
9: CHANNEL SELECT: When this switch is pressed in the
Overdrive Channel is engaged. The Clean Channel is
selected when this switch is out. A footswitch (see #30, rear
panel) overrides this switch. The adjacent LEDs indicate
which channel is selected.
CLEAN CHANNEL: A normal gain channel designed to
give you crystal clear sounds.
10: LEVEL: Sets the output volume level from the Clean
Channel: in the far-left position there is no output; turning
the control to the right increases the output level.
11: LOW: Adjusts the low frequency output level: to the left
reduces the low frequency output; to the right increases it.
This control allows a range of 20dB at 100Hz.

12: MID: Adjusts the mid frequency output level: to the left
reduces the midrange output; turning it to the right increas-
es it. This control allows a range of 14dB at 700Hz.
13: HIGH: Adjusts the high frequency output level: to the
left reduces the high frequency output; to the right increas-
es it. This control allows a range of 27dB at 10kHz.
14: DSP LEVEL, OVERDRIVE: Adjust the amount of dig-
ital effects for the Overdrive Channel with this control: in the
full-left position the output signal is "dry" (no effects); rotat-
ing the control to the right increases the amount of effect.
15: DSP LEVEL, CLEAN: Adjust the amount of digital
effects for the Clean Channel with this control: in the full-left
position the output signal is "dry" (no effects); rotating the
control to the right increases the amount of effect.
16: INSERT LOOP: Connect an external effects device via
this jack. 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. This is a mono pre-chorus
effects loop.
17: CHORUS ON/OFF: Turn the Chorus/Expander on and
off with this switch. When the switch is pressed in, the
Chorus/Expander is active. A footswitch (see #31, rear
panel) overrides this switch.
18: CHORUS/EXPANDER: Select between the built-in
stereo chorus or the "expander" circuit with this switch.
When the switch is pressed in, the chorus section is select-
ed. When the switch is out, the amplifier's expander circuit
is activated, giving the sound a wide-open, "spatial" effect.
In order for either effect to be active, the Chorus On/Off
switch (#17) must be pressed in.
19: DEPTH: Set the intensity of the chorus effect with this
control: in the far left position there will be almost no cho-
rus; as you rotate the control to the right the amount of
effect increases.
20: RATE: Set the speed of the chorus effect with this con-
trol: to the left for slow, smooth "phasing" sounds, to the
right for faster "vibrato" sounds.
21: PROGRAM: Displays the DSP program in use.
22: MODE: Select the DSP program with this control. The
selected program number will appear in the Program win-
dow (#21).
23: POWER SWITCH: Turns the amplifier ON in the up
position, off in the down position. The Channel LED for the
selected channel will light when the amp is switched on.
