Buzz Feiten Mod
as far as the holes are concerned i just filed them (ever so slightly, i mean such that its barely even visible) to an oval. that way, if i ever do need to go back to stock i just loosen the screws on the nut, slide it back and put a 0.03" shim between it and the fingerboard (although i cant figure why id ever do that). also, id like to address the system as a whole:
ok, the idea is to get every fret as in tune as possible right? well, if you just follow the directions of the patent, you will do as follows for an electric guitar -- because there are different specs for each type of guitar (ie. nylon acoustic, steel acoustic, electric, bass, whatever).
move the nut 0.03" forward
tune and intonate as follows
open 12th fret
E 00 00
B +01 00
G -02 +01
D -02 +01
A -02 00
E -02 00
now, this is all a great starting point, but i found that when done to these specs it could still be a little closer because the whole thing is based on the idea that strings go sharp when you press them, well, that means that string action and gauge are the sole determinants of the specs needed for each guitar. so when feiton does it, he has very specific calculations about the ~0.03" -- it might me 0.02" or 0.04", or anywhere in between. but since most of use dont have the luxury of the knowledge of his formula or the measurement and cutting tools, we make do. so basically i take each string, testing every fret (and youll see that the most out of tune are the highest frets, so i usually base it on 17-24), i fine tune the intonation from the specs to what each string needs to be the closest in tune that it can be. it takes time and patience (after about my fourth time i was up to doing the whole thing in about 2 hours), but i works. a tuner doesnt lie. i tested every fret on both my 7v and my UV777, and at the 24th fret im only sharp 3 cents. and that trickles down the fretboard as about 2 cents sharp at 19 and about 1 cent at 17. i mean a guitar is a guitar, so its never gonna be 100% perfect -- but 3 cents is nearly inaudible.
i did all this because i am always fine tuning and adjusting my action, and i cant afford to send my guitars to feiton every time i touch them.
