Newbie to the forum. I bought a mesa amp at a pawnshop about 17yrs ago. I played 99.9% acoustic straight through a PA the last 17yrs and have decided to dust off the mesa and pull out the Ibanez roadstar II that I bought at the same time. Could someone help me date my amp and tell me the value? I also have noticed that the pots are stratchy. Any suggestions for cleaning besides being raped at a music store? It has 11245 stamped on the back of the amp. It's a cream color with 1 MS-12 speaker. I don't see any kind of model name or number on the front like other pictures of mesa's I've seen. I couldn't figure out how to attach a photo.
