first off, it's hard to go wrong with fishman. the amplifier is perfect for what I'm using it for. it's big, loud, and fights off feedback with the right settings dialed in. I use it for small jazz ensemble stuff and bigger groups (blue grass/rock type of music). I've only had it for a short period of time. a few rehearsals and a gig. all has been great thus far. also, sam ash did a fantastic job handling a return for me. I give the store 5 stars also.
