This vintage Carvin amplifier is almost like new. I just replaced the tubes with brand new ones from Tube Depot, but the originals are included. This amplifier features pentode and triode modes (using five tubes or using just three). In pentode mode you can easily gig it. In triode mode it sounds great in the bedroom and breaks nicely at low volume. It also has spring reverb. But it’s not going to come close to today’s digital. Also included is the original manual. The tweet tolex is perfect but there’s a very small what looks like a slightly oily fingerprint on the bottom of one side of the cabinet. I tried wiping it off with Dawn but I didn’t want to risk possibly damaging the tolex tweed which is perfect other than that slight discoloration. It’s virtually perfect. This was probably a closet Queen it doesn’t look like it was never taken out. No scratches dents dings or anything. Those white tabs on the corner are stick on velcro they hold a protective plywood over the grill.
