COMP
COMP, for compression, utilizes old school, all-analog, FET-based technology, which is inherently warmer, more transparent and musical.

REVERB
Dedicated Reverb function emulates the rich ambiance of open spaces, ranging from room to hall. 

DLA/CHR
DLA emulates a warm sounding analog delay. It features Time and Repeats controls and dedicated Tap Tempo footswitch. CHR is a preset chorus based on pitch-shifting technology for a more natural, 12-string-style sound. 

TUNER
Chromatic Tuner is within the EFX section. You simply hold down the TAP/TUNER footswitch to engage the Tuner, which simultaneously mutes the signal path.
