Framus Cobra 4x12 Cabinet

Build quality is pretty generic but solid, on par with or maybe a tiny bit better than 1960 cabs. Not sure how the metal grill will affect things but I'm assuming you're going to take that off first thing.
 
Go through my post history. I did nothing but complain about how much I hated it for a year. I loved it at first, but I grew to hate it very quickly. I've had a Mesa 4x12 since and I don't have a single complaint.

Edit: Also might be worth it to mention the speakers were replaced with V30's by the previous owner
