Bellows

Controls, jacks, and indicators

Level

Use the Level control to adjust the output level by setting the bias voltage of the transistor. A small amount of noise while dialing this in is perfectly normal.

- Drive

Use the Drive control to adjust the input gain of the device for different levels of dirt. You’ll find that it the sound is thinner and cleaner counter-clockwise and thicker, with more growl, clockwise.

Switching

Bellows uses mechanical true bypass switching.
