Control everything from playback and pause to loop, slow motion, fast forward/rewind, all at your feet! No need to stop what you're doing during practice, making it incredibly convenient for guitarists, drummers, and wind instrument players alike. Repetitive phrase practice and ear training efficiency will increase dramatically. I purchased it but haven't used it much. This is a highly recommended unit for anyone looking for one.
