For those awaiting the arrival of a new industry-leading looper, the wait is finally over. Introducing the RC-50 ? the most feature-laden Loop Station BOSS has ever built. Its the best live looping tool ever built for that matter. Housed in a spacious seven-footswitch floor unit, the RC-50 lets you manipulate three stereo phrase tracks simultaneously, with each track supporting multiple overdubs. In other words, you can record phrase upon phrase, one by one, on each track, resulting in a monstrous stack!
