Volume

0–100

Adjusts the volume and distortion of the amp.

Bass GUITAR AMP: 0–100, BASS AMP:-100– +100

Adjusts the tone for the low frequency range.

Middle GUITAR AMP: 0–100, BASS AMP:-100– +100

Adjusts the tone for the middle frequency range.

*If you have selected “MATCH” or “VO DRV” as the type, the middle control will have no effect.

Treble GUITAR AMP: 0–100, BASS AMP: -100– +100

Adjusts the tone for the high frequency range.

Presence

0–100

This can be selected in the “COSM GUITAR AMP” or the “VO+GT.AMP” algorithm.

On/Off

OFF, ON

This parameter turns the ring modulator effect on/off.

Frequency

0–100

This adjusts the frequency of the internal oscillator.
