Professional studio sound in a small package. The NOS 3080a chip works is by a signal-limiting processor that varies the gain so that your output stays at a constant volume. Also the board that is used has silver solder traces for the ultimate in clean sustain. We use high quality box caps to get clearer studio sound. This pedal is true bypass and comes with a lifetime warranty on labor as do all DreamTone Pedals! If you like a Ross or Dyna Comp then you will love this pedal!! It is build on a original Dyna Comp board but uses hand selected parts and Some Ross modifications to make it the ultimate in IC compression! This is the same pedal as our pro comp but some components have been changed for bass tones.
