Okay guys - here's the update (if anyone's interested)
I've got a Peavey Classic 50/50 coming tomorrow (just like yours Jonathan) - I'm pretty excited about it. I'm paying £250 including personal delivery to my house. I don't know how good a price that is, but anyway the Peaey seems like the most versatile and value for money option in poweramps, period.
It's also got a load of features, which will help me out with any changes in my setup (since it's stero i could run multiple preamps...damnit don't tempt me). Also i was very much attracted by the resonance and presence controls, however, i don't know how much effect they'll have. I'd ask you for a review jonathan, but since I'll have the genuine article tomorrow it hardly seems worth it :D Any suggested settings? Do you think it'll work well with my Mesa V-Twin?
