It is equipped with a footswitch button that allows the use of all functions (record, undo/redo, stop, and delete) through different foot commands: press once to record, press again to play the loop, and once more to add another layer; press and hold to undo a layer and press and hold again to redo. Double press to stop and then press and hold to delete the loop. All loops are produced in uncompressed, high-quality 24-bit audio. The Looper provides 5 minutes of looping and unlimited overdubs and has an extremely small footprint to fit any pedalboard. It also allows the "dry sound" to pass through without ever being converted to digital, preserving the original tone with zero latency via Analog-Dry-Through, as well as true bypass. The Looper can save loops after a power outage or unplugging the power adapter. This product requires a 9V DC adapter which is sold separately. Dimensions: 48 x 48 x 93 mm.
