Select Knob – turn to load a Modulation effect Model.

Speed – directly controls how fast (or slow) the modulating waveform sweeps.

Tap – set this to OFF to have this effect ignore tempo, or pick a note value that you’d like your speed to match; works with the Tap button/footswitch and the Tempo knob.

Tempo – Shows the tempo that’s been set by Tap, and lets you fine tune it.

Mix – controls the ratio of wet (effected) to dry (non-effected) sound that is heard.

Depth – controls the overall amplitude of the modulating wave, which usually determines just how intense the effect will be.

Bass – bass tone control.

Treble – treble tone control.

Config – allows you to choose the position of the Mod pedal in your signal flow: Pre
