I've fooled with a couple of multi-effects processors and got this really cool delay effect by twisting the delay speed quickly back and forth--sounds like a cross between lasers and scratching a vinyl record. Looking for a lo-fi delay capable of that and one that has some more whacky capabilities along those lines--Something really digital and pixelated--I'm into weirdness and noise. Recommendations for lo-fi digital delays? Thanks. Edit: Anyone had experience with the Boss RV-3? Sounds ideal.
