This is a feeler as I'm not all that excited about selling this bad boy. Added gut shots here: http://www.emike.net/jmp50 This is a 69/70 (Can't say 100%) Marshall 50 watt small box aluminum panel. The "A" in the serial means 69 or 70 so who knows. The famous Rosemary is on the tag on the chassis. Now this thing sounds like a vintage Marshall should with no issues at all. The tolex is a little beat up on the corners. To me that adds some mojo and I would never dream of re-covering such a collectable amp. The guts look good and no rocket scientist have changed it up thank God. SOLD Here are a few pictures I have on hand.
