4 mono loops or 2 stereo loops in an enclosure that fits under the smallest pedalboards - only 22mm thick. Plus a USB MIDI Interface! This MIDI-controlled bypass looper and USB MIDI interface is unmatched for its compact size and its affordability. True bypass loops, and a stereo buffered output with JFET muting for silent switching. Split-Y TRS to TS cables needed to access 4 mono loops.
