I'm a relatively new bassist, but i'm going to be doing some small gigs soon and I need a new amp (besides my practice one). I live in NYC so it can't be something that I'll have trouble dragging around with me. I've been looking around, but i'm a little overwhelmed with options so what size/wattage should i be looking at, any brand suggestions, and any specific things I should look for in an amp? (I play on a fender 4-string p-bass in a grunge/rock band (no pick), and I use my boss distortion pedal alot.. if any of that helps) Thanks!!
