I'm in the market for a new amp very soon. I want a light combo and I dig these Gallien Krueger MB series combos. I'm torn on a final decision. Should I get the MB212? Single combo with 2 12's and a 500 watt amp. All in one package. Or Should I get the MB115 with an MBP115 powered extension? Both have 15"ers and 200 watt amps on board. I can run a single for quiet/smaller gigs and both for bigger gigs/practice. Just for a little background, I'm in a 4 piece cover band. We are all on inears and I run through FOH.
