PREAMP CONTROLS/DIRT CHANNEL

DIRT DRIVE

To adjust the input drive of the dirt channel use the Dirt Drive control. The
control range of input drive is 0 to 11. When set at zero, no signal is allowed
to enter the dirt circuits so you will have no output. A little bit above zero
will provide a warm overdrive sound. As you increase the control, distortion
drive increases. At eleven, maximum signal and crunch is achieved. Set this
control to get the right amount of overdrive or distortion in the dirt channel.

THRUST

Thrust is the bass frequency cut and boost filter control. A (+)12 dB boost in
gain and a (-)12dB cut in gain are the maximum ranges. At zero, (12 o'clock) the
filter is flat. the center frequency (the actual filter frequency) is 180 HZ.

MID VOICING

To control your midrange tone use the Mid Voicing control. A (+)12 dB boost in
gain and a (-)12dB cut in gain are the maximum ranges. At zero, (12 o'clock) the
filter is flat. the center frequency (the actual filter frequency) is 850Hz.

EDGE

High end frequencies are controlled with the Edge control. A (+)12 dB boost in
gain and a (-)12dB cut in gain are the maximum ranges. At zero, (12 o'clock) the
filter is flat. the center frequency (the actual filter frequency) is 4.00Khz.

DISTORTION LEVEL

The Distortion Level control sets the final level of the Dirt Channel. Set this
control so your Signal LED is lit while you're playing and the Clip LED lights
with sharp attacks. Be careful not to set this control to high because you might
clip the digital effects. Monitor the digital section by moving the Mix slider
fully to the right and listen to the output. After you have set your input gain,
set your Mix control.
