HI everybody! I bought a very old Selmer cabinet a few years ago I think this cab is from sixties but i´m not sure... inside, there are two celestion greenback in very good appearance, and sound is good. I think one is from 1970 and 1972 respectively I'm not sure I want to sell it but, someone wants to buy this cab to me What price do you think is fair? what do you think of this cab? I trying to decide whether to sell or keep a good collector's item more info in pictures thanks!
