Everyone needs one of these. Very similar to all the variations on the Dallas Rangemaster pedal, this is a single Germanium transistor booster with tone and output controls. Includes the 3PDT footswitch for true bypass and battery disconnect. All you have to do is supply the box.
Man, is it ever fat. Really ballsy distortion. A real fun, quicky project.
Here's what you get: Circuit board, parts, 9V battery with snap, jacks, pots, knobs.
