I have never purchased an acoustic amp before, so I'm unsure what I should be looking for! Ideally nothing larger than a 2x12, preferably something smaller but still can be loud. I haven't played on a looper in a while, so I'm unsure if there are any advantages of one over another (Boomerang Vs. Digitech Jamman vs. Boss RC looper). Looking for something i could create a rhythm loop , play that over while I do another harmony/lead/etc. Maybe I'll expand into multiple layers too. Any suggestions would be greatly appreciated!
