The Front Panel:

1. POWER (not shown): This switch applies
AC voltage to the amplifier, and should always
be turned on first. The switch lights up when
the AC power is on.
2. STANDBY (not shown): This switch acti-
vates the amplifier, and should always be turned
on last. The switch lights up when the high volt-
age power is passing through to the tubes.
NOTE: When you first power up this
amplifier, leave the Standby switch OFF
for at least 20 seconds. This gives the
power tubes a chance to prepare them-
selves for action.
3. PRESENCE: Increase the level of upper har-
monics with this control. The presence control
allows a boost of up to 5dB at 10kHz.
4. EFFECTS LOOP PAD: This switch activates
a 12dB pad on the effects send signal and cor-
responding gain recovery on the return. In the
"out" position the signal is full strength which is
best suited for line level rack mountable effects.
With the switch "in" the signal is lower which is
best suited for foot pedal type effects.
5. EFFECTS LOOP SWITCH: This switch con-
trols the effects return signal of the effects loop.
The loop is only active when the switch is
pressed in. When a footswitch is used, this
switch is disabled. The adjacent yellow LED
glows when the loop is in use.
6,7. REVERB 2, REVERB 1: Adjust the amount
of reverberation on each channel with these
controls: at the "0" position the signal is "dry"
(no reverb). As you bring the control up, the
amount of reverb increases.

Channel 2:
8. MASTER: Set the output signal level of chan-
nel 2 with this control. At the "0" position (full
left) very little or no signal will be heard; as you
bring the control up (towards center) the output
level of channel 2 increases. Use this control
along with your guitar's volume and the channel
2 gain control (#12) to produce a wide variety of
sounds.
9. LOW: Adjust the bottom end response with
this control. The low control covers a range of
15dB at 100Hz. This sets the amount of heard
(and felt) from the amp.
10. MID: Adjust the midrange response with this
control. The mid control covers a range of 13dB
at 500Hz. This controls the "voice" of your gui-
tar.
11. HIGH: Adjust the high end response with
this control. The high control covers a range of
10dB at 10kHz. This controls the "bite" of your
guitar.
12. GAIN: Adjust the overdrive (distortion) level
with this control. With the control towards "0" (to
the left) the signal is relatively clean. As you
bring the control towards "5" (center position)
the distortion increases, along with the overall
output level. Keep turning the control towards
"10" and you'll increase the distortion even
more.
13. CHANNEL SELECT: Switch between chan-
nels with this push-button switch. The adjacent
amber LED glows when channel 1 is selected
(switch "out"), the red LED glows when channel
2 is selected (switch "in"). When a footswitch is
used for channel switching, this switch is dis-
abled.
