Hello all. Just a quick question. My wife and I have a small act, acoustic guitar and mandolin, and for the last s6 month our son has been taking bass lessons so he can join the act. We will be playing through a small PA. We aren't talking Pink Floyd. We need to get him a small bass amp that doesn't cost a zillion dollars. I have been looking at Sweetwater and Reverb for used amps. There seem to be a lot of Fender Rumble amps that are fairly cheap. Any recommendations? I want to add that my wife and I are on social security and are retired. We don't have a lot of money to spend.
