You definitely can pop off the last layer in the loop stack, but my particular pedal seems to require another accessory in order to be able to do that (there's a separate pedal you attach to this one).
I've enjoyed my Boss RC-50 (a nice upgrade to the RC-20 I had prior) as a live-looping guitar + vocals pedal for years. It makes it easy to create and layer loops, even when only using the built-in foot controls. Highly recommended.
I loved the song video in this post and it’s inspired me to try a little of this. Is there a good software solution for this? (Bonus points for Linux support)
