i have about three hundred bucks to get a new head with. i need the head on saturday. the only problem is, i don't know what could power my Kallien Krueger GLX 8x10. it's a 4ohm cab and it can handle 800 watts i think? i play in a pop-rock band and we're playing bigger and bigger venues as time goes on. i'm looking at the gallien krueger backline 600 and the acoustic b200h, the b00h doesn't seem like it would be enough to power my cab.
