FRONT PANEL FUNCTIONS

1 2 3
1. POWER SWITCH
Turns the amp on and off.
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 '1'
position.
The standby switch should be set to the '0'
position during breaks in performances instead
of leaving the amp on full power.
3. HIGH/LOW OUTPUT
Choose between high output (100W) or low
output (50W). Low power mode produces a
slightly warmer, rounded tone.
4. PRESENCE
Adjusts the high frequencies of the power amp.
Increasing the high frequencies adds more bite
to your sound.
5. BASS
Adjusts the low frequencies of the amp. It will
add bottom end and depth to your sound.
6. MIDDLE
Adjusts the mid frequencies of the amp, giving
you anything from scooped mids to a fat and
full sound.

7. TREBLE
Adjusts the upper frequencies of the amp. Your
tone will get brighter as it is turned up.
8. OUTPUT MASTER VOLUME / CHANNEL
SELECT
Adjusts the amp's output volume. Pull the
control to engage the lead channel.
Note: The lead channel can also be switched on
and off using the footswitch.
9. LEAD MASTER VOLUME & LED
Adjusts the output level of the lead channel.
The light illuminates when the lead channel is
active.
10. INPUT GAIN / RHYTHM CLIP
Adjusts the overall sensitivity of the input
circuit. Pull the control to engage the rhythm
clip circuit. The rhythm clip circuit produces
heavier, more driven tones.
Note: the apparent drop in volume when the
rhythm clip is active may be overcome by
turning up the output master control.
