I had a gig last night in Edinburgh where the house Bass amp is an ashdown ABM300 with a 4x10. I've played there a few times and have never got an onstage sound I've been happy with - the stage is very small and I'm right on top of the amp. However, Ian Petch - another of our scottish brethren was there and said the offstage sound was excellent and he'd be more than happy with that amp setup - For comparison, he has the last pre-gibson Trace elliot 4x10 combo. Interestingly, He said he couldn't really tell the difference between my fretless rogue and my fretted epic ;-(
