maximum performance.

switch. Fine-tune the amount of distortion with the adjustable trim pot on the pedal's OUTPUT side.
Ultimate Low-End Sculpting - Use the "Bass" control (100Hz shelving boost) in conjunction with the
"Focus" (high-pass filter) control to have the final say in the shape, punch, and detail of the low end.

on-the-go playing.
