So I have a completely acoustic, no electrics at all, guitar, and I'm interested in investing in a set up that will allow me to play with a loop effect and plug into an amp. Any recommendation on a good pickup and looper/sampler that I could use? I like the looks/ features of the Digitech JamMan.. would I need to install an active pickup to use that? or passive? What about mic ing the guitar and then running the mic through the loop, then the amp? Just kind of lost amidst all these options.
