Very first post on the RV Forum, and of course the very first section I go to is this Music section!
I?m a long-time gigging acoustic musician and have two recommendations for you all ? the Loudbox Mini Charge and the Bose S1 Performer. I just went through this evaluation process and bought the Bose. Both of these are fantastic amps, and both are battery-powered ? with an amazing 11 hours of playing time through the Bose (and the Fishman is comparable). Slightly different features for both. The Bose is a little spendier, I believe (and I?ll recommend Swee****er.com as a great on-line source for any of you who don?t have a music store nearby ? no affiliation whatsoever, just a very satisfied customer). Both have their own batteries ? you?re not replacing D or AA batteries or anything like that, and both re-charge through just being plugged in to a 110 outlet. Both are also Bluetooth-enabled, so you can play music from your phone or iPad through them (and they sound great) and, of course, even play along with the music if you want to. As I said, both have some slightly different features so you?ll want to check them both out well. But both brands are also well known for their first-rate quality and customer service. Both crank out a ton of volume for their power ratings (Fishman 60, Bose 40, I believe ? although wattage is not a direct indicator of volume ability) and are really amazing amps. There are cheaper options out there for sure but for my money, these two are at the top of the list. Good luck!
