So I've decided to breathe new life into my dad's old LP custom. He got it as a teenager in the seventies and it's in pretty rough shape. He traded the original bridge and tailpiece for chrome ones with one of his buddies and at some point he replaced the original pickups with single coils (unfortunately, he didn't keep any of these parts). He played the hell out of it, but after he passed away it sat in its case at my mother's house for many years. I'm giving it some TLC now, cleaning the grime off the fretboard and polishing it though the finish is a bit chipped here and there and the binding is completely yellow. The selector switch seems to be faulty (it won't stay on "rhythm" for some reason) and the input jack was pushed into the body, though it was an easy fix. Some of the frets are pretty worn out too though I haven't had too many issues playing it. Right now I'm a bit torn between keeping it is as it is (as he played it) or trying to restore it as close to stock as possible. Any thoughts? I'm not sure about the year he bought it either, I'm guessing mid-seventies from the look of the tuners and the un-dotted "i" on the Gibson logo.
