Re: R8/R9 Fret Wire Size
My 2003 R9 frets are 0.100" wide and just under 0.050" high (2.54 wide by 1.27 high in mm) in finished condition (they were a tiny bit higher when I bought the guitar, they took a lot of leveling.) Same as my 1990 Standard, although the crowns were maybe a little rounder, and the set-up was abysmal in comparison.
It's what they call Medium Jumbo IIRC. Now all we need is for someone to measure an R8.
