Spent the day at the recording studio, going through various ampeg amp Sims. Wasn't 100% happy with the tone. Re-amped the Di through the Ashdown and a trace 410, shape on and slightly boosted mids, and that was it - the sound I was after and so much better than what I had before. I've never usually engaged the shape button live, but it worked so well recording I might have to start using it live.
