Hi all loving the forum, looking for some tips with a new to me modified 69 SG. Bought this last week knowing it had some stories to tell and fell in love with it quickly. It’s a 69 special with a patent number sticker humbucker in the neck. The routing for the humbucker seems to be fairly minor and more of a chiseling than a routing. Tubners swapped out for grovers and a leo quan badass bridge. Questions: What’s the best way to care for the nitro finish? It’s pretty dirty but don’t want to ruin it. Same for fretboard care, my fingertips are gross after playing for 10 mins. Any experience with worn frets? I’ll take it to my luthier and talk it over with him,but I’m wondering if there are known issues with the neck binding during a refret. Or something else specific to this. Is this the original case? Anything else jump out?
