Back in the late 70's I had some guy bring a Tele into the shop who wiped the rosewood fingerboard weekly with a liberal swipe of motor oil. The fingerboard had turned into sponge, and the frets could be popped out with a fingernail. Down the bottom of the fret slots you could see oil had puddled there. Plus, it reeked of rancid oil. The oil was starting to discolor the maple.
I sliced off the rosewood board, and bathed the maple in lacquer thinner several times a day for a week or so until I could no longer smell the oil, and it didn't blot off onto a paper towel. Planed the neck for a fresh surface and glued on a new rosewood board, then fretted as usual. After I refinished the neck with amber lacquer, I handed the guitar back to the client with a hefty bill. I also threatened him with death if he ever used motor oil again on any guitar.
Love this guitar! didnt really have good experiences with floyds in the past , most were cheap metal and that and sounded kinda muddy loud;( this is super smooth as a fixed bridge and the tones are great and super clear on the lead tones.
I use a few drops of Fender neck oil on the fretboard occasionally to make it look and smell good but mostly for the practical purpose of making the strings glide silkily over the frets during bends. I'd never put any kind of oil or finish on the rest of the neck because bare wood already feels and sounds good to me.
NO, No No Old English or Formby's Lemon oil for over 30 years ( If U wanna take some of the back finish off , will be faster than ANYTHING You've ever felt . I dont care if an Ax is brand New , Im a serious Guitar player not Collector ( If it's a super- Collector guitar dont do Crap to it .
