Used Interstellar Overdriver overdrive pedal. Vg condition with box and velcro on the bottom. Designed to blast your amp with your sound. Beautifully transparent and based around a discrete circuit, this pedal is all about the natural, wonderful sound of turning an amp up too loud. It’s specifically constructed to work the same way as old tube amps – the more you turn it up, the better it sounds. The drive knob sweeps from a slight boost to a beautiful, harmonically rich overdrive. For more control, kick back the output volume with the MASTER knob while retaining the sweetness. There are a lot of pedals out there attempting to do this simple, beautiful thing, but this one just might do it best.
