Hey all, I'm, a relative newbie bass player. I'm a little confused as to how much amp power you need for the following situations: 1. Jamming with guitar(s) only. 2. Jamming with drums and/or guitar(s). 3. Performing live (with drums) in a small venue. Right now i have a Fender Rumble 60 (is it 60 watts? I heard it was 100...). How far will this take me?
