I'm currently using an Orange Ad200b mk3 with two Ashdown cabs, a 115 (250w) and 210 (200w). My aim is too cut down on the current size but not in volume or quality hence I'll be purchasing an Orange obc115 rated at 400w. Will I notice much difference in volume achieved? I use a fair bit of gain so is there any chance that I may push the cab too much? Cheers in advance.
