This effect module emulates the effect that different variations of digital sampling can have on an audio
signal.

Lower values indicate lower decimation frequency (more decimation, more aliasing).
Pedal Sample Rate Decimation
A sample rate decimator effect controlled by the expression pedal.
Bit Reduction
Higher values indicate lower resultant bit depth.
Pedal Bit Reduction
Bit Reduction effect controlled by the expression pedal.
Off
Indicates that DIGFX is off.

In this position, the display shows you the output level of the current program.
Level

gain is the point at which the level of the output is the same as the level of the input.
Pedal-Controlled Level
