guitar to the amplifier using a shielded
instrument cable.
2.

level of the Clean channel.

CHANNEL Select: Push in this switch

level.

the output by 10 dB at 900 Hz. This
adds more punch to the midrange fre-
quencies.
6.

TREBLE: Use this to adjust the output
level of the high frequencies. The adjust-
ment range is 12 dB at 6 kHz.

level of the mid frequencies. The adjust-
ment range is 10 dB at 1 kHz.

10. PRESENCE: Push this switch in to
adjust the overall brightness and punch
of the output signal.
11. REVERB: Use this to adjust the amount
of reverb. Fully counter-clockwise is
"dry" (no reverb). Rotate clockwise to
increase the amount of reverb.
12. LAMP: This illuminates when the ampli-
fier is turned on.
13. ON/STANDBY Switch: Use this switch
to activate the amplifier after the On/Off
switch (14) is turned on.
Always turn this switch OFF first, and
ON last! Turn the On/Off switch (14) 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 tubes.
14. 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 (13) on at
least 30 seconds after turning on the
On/Off switch.
