I've been considering swaping my svtcl for an ashdown abm 300, or 500. Any experience on how loud these heads are in relation to their power rating? Fair, conservative, inflated etc. I play through and ampeg 8x10 cab so my cab setup is plenty efficient. I play in a rock band with two boogie half stacks, a pretty loud drummer and a keyboard player. Any help would be appreciated as to whether or not you guys think an abm 300 would do the job. I'm not looking for prestine clean headroom so some dirt isn't a problem.
