That’s a very cool trick - I used a feedback loop pedal with a trimmer pot. I will have to experiment with it more. It has some dominant frequencies depending how the sliders are set. Might be a fun thing to run through some of my other gear. The sequencer idea is a good one, as would be programming your own patterns
Wow-- that is really neat. I find it hard to get a pleasing sound but there are sweet spots. It’s amazing how much variance you can get to. Thanks for highlighting this for us.
