So I'm pretty much clueless about amps because I've always just borrowed the school's amp but I literally used it to the point where it is falling apart. Now I've been asked to play for a pit orchestra and the only amp I own is my little starter amp. I play mostly jazz stuff. I have a Fender Marcus Miller Jazz Bass and a Squier Fretless Jazz Bass and I play in Marching Band, Jazz Band, and (most importantly at the moment) Pit Orchestras. I'd appreciate some replies to this as I don't think it is something that you can really research efficiently in the short amount of time I have. Thanks.
