I was looking up some info on loopers with drum tracks last night and fell down the rabbit hole. The attached chart should save you the trip. It's a brief comparison of features on loopers under $200 (USD, March 2017 new pedal prices). I used Amazon prices because it was convenient. I've left out a few things on purpose, mainly to keep it on one page: More expensive loopers - this is, after all, Squier-Talk. Many <$200 favorites and clones - I had to stop somewhere. Links to merchants or demos - those may change. Reviews. If you'd like those, send me the pedals (returns not guaranteed). Other features that I didn't think of including. Anyway, if you have other suggestions (EDIT: or corrections), post them in replies with as much info as you can to help others out. Don't hold your breath for file updates.
