Compressor
A compressor is used to increase sustain, and even out the volume dynamics in guitar
signal. A compressor sets boundaries for a signal's strength. When a signal exceeds
the set boundary, it is forced back into the set boundary. As the signal fades to a point
where it no longer exceeds the boundary, the compressor expands the signal strength
and increases sustain. The compression parameters are as follows:
Comp On/Off
The STATUS button turns the Compressor (
Attack
KNOB 1 adjusts the length of time it takes for the Compressor to respond to a
signal exceeding the Threshold. Values include:
Ratio
KNOB 2 adjusts the input to output ratio once the Threshold has been exceeded.
For instance, a Ratio of 4 to 1 means that a signal exceeding the Threshold by 4
dB will only be allowed 1 dB of increased output. Higher settings yield a tighter
sound and increase sustain. Lower settings allow better dynamics. Ratio settings
are: 1.2:1 (

KNOB 3 selects the Threshold (

activate the compressor with weaker signals. Higher settings require a stronger
signal to activate compression. Ranges from 0 to 99.

KNOB 4 adjusts the Output Gain (

Other effects can clip if the Compressor Gain too high. Ranges from
