Hey all! New too the forum here. I have a 1993 Set Neck PRS guitar that has been in my friend family for over 20 years. My one buddy pulled it out of a studio that had a fire after the fact. He had a Luther look it over, upgraded the tuners to the Series I locking and now wants to sell it. I would like to take it to keep it in the family and it needs some work for sure. The last time it was worked on was in 1998. The 1st string tuner seems to be broken and not grabbing the string. There are several scuff marks and the screws have some rust/oxidation. Any thoughts? Thanks!
