I use to own a hartke kilo and had the hydrive 410 and 15 cabs. I had nothing but problems with the kilo so i returned it and got a gk 1001rb ii. Do you think i should keep the hydrive cabs and run the gk through them or a set of gk cabs. I was reading somewhere that the gk 1001rb ii has a setting for biamp which i am unfamiliar with. Can i ise this setting with the hydrive cabs or will i need a pair of gk cabs. If anyone coild help me out it would be much appreciated.
