1. INDICATOR
The power indicator will light when the amp's
mains power is switched on.
2. STANDBY SWITCH
The standby switch is used in conjunction with
the power switch to 'warm up' the amp before
use.
Always turn the power on for two minutes
before switching the standby switch to the 'on'
position.
The standby switch should be set to the 'off'
position during breaks in performances instead
of leaving the amp on full power.
3. POWER SWITCH
Turns the amp on and off.
4. SPEED
Controls the speed at which the tremolo effect
oscillates.

through channel 2.

amount of high frequencies (treble) present in
the sound.
7. VOLUME CONTROL (CHANNEL 2)

8 & 9. CHANNEL 2 INPUTS
These are the guitar inputs for channel 2. The
top one is the 'high sensitivity' input for this
channel. The bottom one is the 'low sensitivity'
input (6dB lower).
10. TONE CONTROL (CHANNEL 1)
This controls the tonal character of channel 1.
Turning the tone control clockwise increases
the amount of high frequencies (treble) present
in the sound.
11. VOLUME CONTROL (CHANNEL 1)
Controls the volume for channel 1.
12 & 13. CHANNEL 1 INPUTS
These are the guitar inputs for this channel and
both are identical.
Note: some guitar players prefer to mix the
two channels together by plugging a guitar into
the top (high sensitivity) input of the Tremolo
channel and running a short, screened guitar
cable from the Tremolo channel's bottom (low
sensitivity) input to either one of channel 1's
two identical inputs. The Tremolo channel must
be used as the primary channel.
