This is a Greco Les Paul model. I received it from a friend about 10 years ago, and this year I did some maintenance on the electrical components. Selector switch replaced Front volume pot replaced (knob missing) Jack replaced Pickup cover on the front is damaged. Based on the serial number, it's believed to be from 1990, but apologies if that's incorrect. Operation confirmed. No crackling. Please ask for any additional information in the comments. To prevent any issues after purchase, please feel free to ask any questions you may have. (Modified from original parts)
