Hello all I'm really feeling the GAS for a really punchy head. It'll be run by two GK Neo 112's, so I have the punch in the cab category. I've looked at the GK 700RB-II, just because I'm one who thinks that matching head and cabs look sexy, but am not limited by it at all. Please give me any recommendation, but try to keep it under a $800. If I can get a better bang for my buck by going used, I would definitely prefer it.
