EFFECTS AND PARAMETERS

Compressor Block

COMP
The Compressor is especially effective for guitar since it
smooths out the "peaks" and "valleys" in the sound.
Compression "squashes" the dynamic range of the signal,
making loud signals softer and soft signals louder. Nor-
mally, the Compressor limits signals of widely varying
loudness to a dynamic range more suitable for use with the
other effects. For this reason, compression is effective on
guitar in smoothing out the level differences caused by
uneven picking technique.

This section briefly explains each of the effect types and their parameters. For information on

Determines the degree of compression. Maximum values

result in a smaller dynamic range, where originally loud

sounds become soft, and vice versa. This increases the

Determines the level of the Compressor sound. Higher

settings are used for boosting the overall signal to an

switching the Compressor block on and off.
