Used DigiTech JamMan Looper/Phrase Sampler
 
The DigiTech JamMan is a looper/phrase sampler designed for the performing vocalist and musician. The dual footswitch floor pedal uses Compact Flash memory cards to create seamless loops with virtually infinite overdub capability. Audio can be input from an instrument, microphone or a line level audio source.
Up to 99 loops can be stored on a Compact Flash Type 1 memory card in WAV format, which can later be transferred via USB to a computer for archiving.
 
The JamMan has both a microphone and an instrument input allowing it to be used in a variety of situations. For instance, the pedal can be loaded with a drum track, bass line, solo vocal and harmonies, turning it into a "band in box." It will also slow down or speed up any song without changing pitch.
