I play a 5 string ESP LTD D5. I currently play on a behringer 450 watt combo amp with 2 10". The orignal cones were pulled and replaced with Eminence speakers. I ghettofied it and am runnning a 12" GK Backline 12" combo amp for the low end. i play in 3 different bands. Focus on alot of metal, rock, older rock like MEtallica and stuff and softer stuff like STP and whatnot. The bands i play in are Bass Driven, i drive most of the grooves and provide alot of the sound since the other guitarist sucks and I carry him. anyway, I want to invest in a good cab. I was given a GK 800RB head that has no output signal so I am having it repaired by GK. I want to get a cab that will not only work well with the head but really drive my sound and be able to handle me playing the crap out of it. I play with 2 other guitarist who use a Marshall half stack (full stack at shows) and a Hartke half stack with an additional 12". Help me oh wise bass players - what should I get?
