1. Input: Connect your instrument
here by means of a shielded signal
cable.
2.. Volume: Use this control to
adjust the output level of Channel
A.
3. Treble:Use this control to adjust
the output level of the high frequencies for Channel A. This control
provides an adjustment range of
30dB at 10kHz.
4. Mid: Use this control to adjust
the output level of the middle frequencies for Channel A. This control provides an adjustment range
of 6dB at 600Hz.

the output level of the low frequencies for Channel A. This control provides an adjustment range of 30dB
at 80Hz.
6. Channel Select: This switch,
when depressed, activates
Channel B. Channel A is active
when the switch is in the out position.
7. Gain: Use this control to adjust
the gain for Channel B. With the
control towards the counter clockwise position, the gain is low and
very little distortion is present. As
you rotate the control clockwise the
gain increases, producing more
overdrive distortion and a higher
output volume level.
8. Treble:Use this control to adjust
the output level of the high frequencies for Channel B. This control
provides an adjustment range of
10dB at 4kHz.
9. Mid: Use this control to adjust
the output level of the middle frequencies for Channel B. This control provides an adjustment range
of 10dB at 1kHz.
10. Bass: Use this control to adjust
the output level of the low frequencies for Channel B. This control
provides an adjustment range of
12dB at 100Hz.
11. Level:Use this control to adjust
the output level of Channel B.
12. DSP Mode: Use this control to
select which of the following digital
effects to apply to the signal.
BYPASS no effect
SMALL REV small room reverb
MED REV medium room reverb
LARGE REV large hall reverb
SLAPBACK short slapback echo

13. DSP Level: Use this control to
adjust the level of the DSP effect.
With the control rotated fully counter clockwise, no effect will be audible. As the control is rotated clockwise the amount of the effect is
increased.
14. Presence: Use this control to
adjust the overall brightness and
punch of the output signal.
15. Lamp: This lamp illuminates
when the amplifier is turned on.
16. On/Standby Switch: Use this
switch to activate the amplifier after
the On/Off Switch (#17) is turned
on. Always turn this switch OFF
first and ON last! Turn the
On/Off Switch (#17) on at least
30 seconds before
turning on
the Standby switch. During short
breaks you should turn this switch
off and leave the On/Off Switch on.
This will help prolong the life of the
amplifier’s tubes.
17. On/Off Switch: Use this switch
to turn the amplifier on and off.
Always turn this switch ON first
and OFF last! Turn the Standby
switch (#16) on at least 30 seconds after
