So I pretty much never play my Gibson LP, but decided to pull it out today and do some recording in my DAW. Finished and went to put the guitar away to find that I can't remove the cable. It's stuck. After pulling on it a few times, I didn't want to risk wrecking the guitar as its still near mint, so I unscrewed the plate to look inside. Tried to force it out from the inside, but no luck. Any ideas?
