Used indoors only, and I believe it's in very good condition. Aside from one screw missing next to the power cable (it seems it was never there to begin with), there are no noticeable scratches, and the operation has been confirmed to be normal. It truly has that analog sound, with its thickness and warmth, that's difficult to replicate digitally. As it's a vintage item, there may be some crackling in the knobs, but I don't think it will affect usage. I appreciate your understanding.
