hi there. i've decided to invest in a bass cab and head, because i need to. i've been looking, and i've given myself a limit of $1200 total for the bass and head. i've looked around and the ampeg-b2r head looked good to me. i'm pretty much stuck on what to buy. i saw a used genz-benz 2x15 for 400 bucks. also a genz-benz 6x10 for 500 bucks. i don't know. please give suggestions for i am young and naive!
