The Super Duper 2-IN-1™ has two of ZVEX's infamous Super Hard On™s in one small box, plus a Master volume control that lets you use it as an overdrive/distortion with any input volume. The two channels can give any amount of gain, from a soft bluesy boost in two stages, to a crunchy rock level, to a wild sustaining beast.
This pedal is lightly used and will ship safely in its original box the next day!
