Stereo looper

For those awaiting the arrival of the ultimate looper, the wait is finally over. Introducing the RC-50 — the most feature-laden Loop Station BOSS has ever built. It’s 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. Each track supports multiple overdubs, so phrases can be stacked one by one on each track, resulting in a monstrous layer of looped phrases.

Ultra-long recording time (up to 49 min., mono), 99 patches (3 master loops per patch)
