Jacks: In on the right, Out on the Left
D: Drive. How hard the signal hits the transistors. This has the largest control over the intensity of the distortion. CCW Less Distortion. CW More Distortion.
G: Gain. Changes the sharpness of the distortion. CCW Woolier, CW Bitier.
E: Electromotive Force... sort of, not really... it does change the electromotive force in an antique sense that it changes voltage, from 7v to 18v. When the Gain is dialed, and the E is at 0, it will gate significantly... don't worry it's not broken, the gain just wants more juice! The E & G are very interactive.
I called it electromotive force because I lost my H stamp (headroom), and didn't want another control labeled V. Anyway CCW warmer and softer, CW better articulation and more headroom.
B: Body. Controls the amount of low end in the circuit. CW most compressed, heaviest sounds. CCW for the brightest, cleanest sounds.
Each pedal is hand made, hand drilled, hand stamped and the pedal you receive may be different than the one shown.
Industry standard 9vlt jack, 9v ONLY, no wall wart included, no battery option, isolated power recommended.
