I'm looking for looper pedals that allow you to manipulate and do weird things to your looped samples. Here are the ones I know of: 1. EHX stereo memory man- you can change the speed of your loops, hi-pass filters, etc... 2. El Capistan- sound on sound tape loops 3. Time factor (does a lot of stuttery stuff) 4. Zvex Lo fi looper What else is out there?
