I've guested onstage a few times playing bass just because I love playing bass.. and, yeah, you can't hear jack right in front of your bass cabs, but its just BOOMING out front and everywhere else..
The place we usually play is pretty cool in that all the PA bottoms are underneath the stage.. so, when the bass start pumping, the entire stage floor shakes.. Its pretty cool.. i know ifI was a bass player, I'd be super stoked just about that..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
