Set the Sustain control low, the Tarpit gets dark, with a low gain, almost gated feel. Increasing the Sustain control has a double effect—the Tarpit gets slightly brighter, and the fuzz, sustain, and harmonics all increase.
Turning the Tone control down cuts treble, and boosts bass frequencies; setting the tone control in the middle, or slightly above, gives full guitar and bass frequencies.
The Volume control allows awesome sustain and fuzz at lower volumes when needed…never fear, though, the Tarpit can get as loud as you need it to!
The Tarpit can run off of a battery, or a standard 2.1mm, negative center pin power supply. The in and out jacks are on the top of the pedal, as well as the DC jack to help with pedalboard layout.
