I went into Guitar Center today and they had literally just put this cabinet on the floor. I bought it for $475 (was marked $499). They let me take the back off to check out the speakers but I can't take it home for a month as they have a 30 day hold on used gear before it can leave the store in case it's stolen. I tried it for about 2 minutes to make sure it wasn't blown. Used a BF Bassman and it sounded great. Anyone know what year this is or what it's worth? I like B cabs vs A cabs and actually went in looking for a B cab, so this is great. I'm guessing it's late 70s but I am not an expert on these.
