I was looking at maybe getting a Hughes and Kettner (have to travel a bit to find a place that has them) and i was wondering if the 60watt DFX is a step up from my current Marshall DFX. Or is valvestate/tube the way to go? I play classic rock (Rush) and Power Metal (Galneryus) and i was hoping that this new amp would work better with my effect pedals and have a better clean channel. Any other amps i should try? (I only have about $600 now)
