Heyyy...a few months ago, I scored a Pevey Classic 50 4x10 and have been VERY happy with the goddamned thing.
I play in several bands, and have taken to using the classic for all of my non-metal gigs (including '60's soul, '70's pub rock/Wilko/Feelgood sound and a Tom Petty cover band)
Here's the thing.
The amp does a great big, round Fendery sound, but I sometimes wish it had a bit of that Celestion mid-range bite to it as well, so I've been thinking of maybe changing out a couple of the speakers to get a blend.
So what would be good for that? I'd want to leave a couple of the stock speakers in (blue marvels, I think) so I'd need something that lined up both ohmage-wise but would also stand up efficiency-wise so they'd be heard.
Alternately, I might just pick up another one (or a vintage 30) with 12"s and stick a V30 in there...which is probably what a sane person would do.
