Print Page- Counter clockwise decreases distortion.
Like all of the preamp controls on this amp, each channel is independent. You can have a clean
setting on one channel and a distorted setting on the other channel.
5. Master Volume: This control sends the signal volume from the preamp to the power amplifier.
For the cleanest signal, turn the Master Volume tip high and keep the Overdrive low (but not off).
For the dirtiest signal turn the Master Volume down (but not off) and the Overdrive up high.
6. Channel 1 Indicator (Red): When your amp is in Channel I and the power is on, this L.E.D.
will glow. It's indicating that only the controls on this row will affect your sound.
7. Channel 2 Indicator (Green): When your amp is in Channel 2 and the power is on, this L.E.D.
will glow. It's indicating that only the controls on this row will affect your sound.
8. Tone Controls: The two sets of tone controls allow you to get tile tone coloration you want
from each channel, without affecting the tone of the other channel. The three tone controls-
Treble, Mid and Bass are a standard interdependent circuit. As you increase the Mid control, the
Treble and Bass will yield less range.
Treble Tone Controls: These controls let you change the high-end response of your amp. Each
is a high-pass passive filter that can reduce the signal level 0-38 db, with a 6 db per octave slope,
- Turn clockwise to increase high-end response.
- Turn counter-clockwise to reduce high-end response.
Mid Tone Controls: These controls lot you change the volume of mid. range within a range of
0-12 db. *Turn clockwise to increase low-end response.
Bass Tone Controls: These controls let you change the low-end response of your amp. Each is
a low-pass passive filter that can reduce the signal level 0-15 db •Turning the dial clockwise
increases the low -end response.
Experiment with these controls to rind where they work beat with your guitar and the room you're
playing in.
(Note: If you turn all tone controls "Off" (farthest to the left), no sound will come out of your amp.)
Module Tips:
- When you're using "Low Cut" modules, the Bass controls will have less effect on your sound
because the module is rolling off much of the bass response.
- The "Presence" module will be greatly affected by the treble control. (See pages 7-8 "Preamp
Modules" for more tips.)
9. Reverb: These controls lot you set the amount of reverberation you want in your sound.
- Turn clockwise to increase the amount of reverb.
- Turn counter-clockwise to decrease.
Some players prefer no reverb on one channel only. Can you imagine changing channels with a
footswitch and using another switch to turn the Reverb on and off With two Independent Reverb
controls, you can set as much reverb as you like on one channel and turn the other channel's
Reverb "off" by simply turning the control counter-clockwise.
10. Channel Selector Button: This push button lets you change channels manually The L.E.D.'s
show you, which channel is "On."
If you prefer to use a footswitch, use the Channel Selector Button to put the amp in the green
L.E.D. channel first, then the footswitch will operate.
