VOLUME: Controls the output volume of the circuit. Higher settings will begin to overdrive your amplifier, which can add additional body and smoothness to the fuzzed-out sounds. Crank it up!

DEPTH: The heart of the pedal. This knob is essentially a blend control that mixes in a second transistor gain stage with the first. At the minimum setting, you're hearing the first transistor on its own—cleanish and fat. As you begin to blend in the second transistor, at various points along the way, you will notice more voltage-starved, gated sounds; pseudo ring mod-style upper octave harmonics; and, at max settings, a thinner, more aggressive saturated sound with a ripping top-end attack and huge bloom to the notes.

The Fuzzrite Mini can accept any good-quality 9V DC adapter for use with audio circuits that is filtered and regulated with a center-negative tipped plug.
