TC Electronic Ditto Looper

A compact, easy-to-use looper pedal. It has mono inputs and outputs, plus a USB connection for importing and exporting loops.

It has 5 minutes of loop time, unlimited overdubs, and 24-bit uncompressed audio. The knob dictates the loop level, and the footswitch enables recording, overdubbing and clearing. It's very small, so it should fit on your pedalboard ;-).
