Miniature passive guitar overdrive circuit with a "tweed amp" crunch!
Black Ice Overdrive
Encapsulated in a 1/2" cube, Black Ice circuitry replaces the capacitor on a guitar's tone control. It transforms the tone control into a battery-free overdrive control, letting the player dial in smooth variable overdrive "crunch."
See details below
Black Ice is designed for use with high-output (10K ohms or more) single-coil or humbucking pickups and a 250K control pot. Installation is easy, with no guitar body routing. Instructions included.
Not for use in active pickup systems.
After thinking about it for months, I decided to try the Black Ice passive distortion circuit. I wired it into a Fender Jazz Bass. I was concerned the pickups would not have enough output, but it sounds great!! I may end up putting a Black Ice in all of the touch-guitars I build. Thank you!
