This is a vintage 1986 Marshall Lead 12 3005 Mini/Micro Head which is made in England. It has a single channel and a solid-state amplifier technology. Original owner. While I don't quite buy the hype ( no, it doesn't sound "just like a JCM 800") it is an amazing little amp. I used it for a back up, on the road. Not a museum piece, it has some wear and tear. Original except for a replaced power switch. Works fine. Own a piece of Rock history!
