Tonight I finally got around to experimenting with a technique I read about in Tape Op of producing sound by connecting effects pedals in a loop. There's no musical input here, you just connect them together and work off the transients that are created and then fed back, amplified and effected in various ways, and twiddle the knobs and select sets of effects to change the sound.

1. effect loop feedback sounds 1.mp3 (my harmonist pedal pulls a self-indulgent solo for a couple minutes)
