I really like my Swart AST but sometimes, can't resist the urge to tweak. I'd like to hear from anyone who has swapped speakers in the AST. What did you try and what were the results? Mine has the stock Brit Vintage speaker. I talked to Micheal Swart about options and he said that a lot of folks like the Celestion Gold (which he offers) in this amp. Yes, I tried doing a search, but I couldn't narrow down the results enough to find this specific question.
