Thanks for your comments. To be honest if I had the time available to meet people to try it etc, I'd do it at home.
Anyway, I'm bumping this with a price drop to £1150. I'm not not particularly overjoyed at losing around £500 on an amp I'm actually loathed to part with, but despite it's condition, warranty and little use, it's still a second-hand amp and the price should reflect this. Also a few things have cropped up and the cash whilst not critical, would be useful.
I've had a few interesting trade offers, but I'm not really looking for any more gear at the mo.
If it's not saleable on here for that price, I probably will hang on to it because I know I'll regret selling it later.
