A six-track stereo floor looper with nine assignable footswitches, 49 input effects and 53 track effects.
Watch
The Loop Academy's clip on the RC-600 is about timing, which is the skill a six-track stereo layout depends on most.
Why it matters
Six stereo phrase tracks run at once, and the nine footswitches can be assigned freely across three pedal modes, so the layout can be built around how you perform. Two XLR inputs with phantom power take vocals or a mic'd source alongside the instrument, and there are three stereo outputs. It shared the top spot among loopers for 2025 sales with the smaller RC-5.
Note
BOSS's flagship floor looper, announced October 2021, and tied with the smaller RC-5 as the best-selling looper of the 2025 sales year. Six stereo tracks, nine assignable footswitches and a large on-board FX selection.
