im thinking of getting a berg nv610 cab for a long time now and may pull the trigger real soon as i have a new band in the works. now head wise im still at a loss. i was first considering a gk 1001rb-II head but after further thought i don't know if i really want it because i like a nice warm tone, and from what i read gk has a more clean sound. now i've been considering the ashdown evo 500 II head. i hear ashdown can get a nice warm sound and is more versitile. has anyone played the ashdown through a nv610 or even owns one?
