The Front Panel:
1. Input: Connect your instrument here by
means of a shielded signal cable.
2. Clean Volume: Use this control to adjust
the output level of the Clean Channel.
3. Clean/Overdrive: This switch, when de-
pressed, selects the Overdrive Channel.
When this switch is in the out position, the
Clean Channel is selected.
4. Overdrive Gain: Use this control to
adjust the gain of the Overdrive Channel.
With the control towards the counter clock-
wise position, the gain is low and very little
distortion is present. As you rotate the con-
trol clockwise the gain increases, produc-
ing more overdrive distortion and a higher
output volume level.
5. Treble: Use this control to adjust the out-
put level of the high frequencies. This con-
trol provides 12dB of cut or boost at 6kHz.
6. Boost: This switch, when depressed,
increases the output by 10dB at 900Hz,
giving the middle frequencies more punch.
7. Mid: Use this control to adjust the output
level of the middle frequencies. This control
provides 10dB of cut or boost at 1kHz.
8. Bass: Use this control to adjust the out-
put level of the low frequencies. This con-
trol provides 8dB of cut or boost at 150Hz.
9. Presence: This switch, when
depressed, increases the output level of
the high frequencies by 8dB at 10kHz, giv-
ing a more “glassy” sound to the amplifier.
This helps the output of the amplifier cut
through “acoustically dead” rooms.
10. Overdrive Level: Use this control to
adjust the output level of the Overdrive
Channel.
11. Reverb: Use this control to adjust the
amount of reverberation applied to the sig-
nal. With the control fully counter clockwise
no reverb is applied. As you rotate the con-
trol clockwise the amount of reverb increas-
es.
12. Lamp: This lamp illuminates when the
amplifier is turned on.
13. On/Standby: Use this switch to acti-
vate the amplifier. The On/Off switch (#14)
should be turned on first. Allow 20 seconds
for the amplifier to warm up before turning
the Standby switch on.
14. On/Off: Use this switch to turn the
amplifier on and off. This switch should be
turned on at least 20 seconds before turn-
ing the Standby switch (#13) on.
