Hey Cactus.... on the topic of the Play Acoustic. A guitar setting FYI . Just tweaking with guitar  settings ( mine goes into a Fishman  Artist). On the Mix menu, the first parameter " Guitar Level": big difference between setting that above-10...at even - 8 up to 0db, there is a lot of hissing, and , as I turned it down to the -10, the hiss just disappeared and my tone was great, even if I jacked up my guitar pickup....sensitive to just a couple of db...
