Nabbed this GK 1001RBII head last night as a birthday present to myself. It's in excellent condition and sounds fantastic! Got a great deal on it too. So now my question is what cabinet to pair it with. I have an Ampeg PF115he cabinet for my PF350 head but now I'm not sure if I will keep the Ampeg gear. Should I get a GK cabinet to take advantage of the horn biamp feature? Does it make that much of a difference to the sound? How do the MBE cabinets compare to the other GK cabs? I like the light weight design but will they hold up with this head? This is my first piece of GK equipment so any help would be appreciated.
