How It Works How It Works Features How To Identify A BFTS Guitar Tuning With The BFTS Tuning By Ear F.A.Q. How It Works
The Buzz Feiten Tuning System solves tuning and intonation problems with 2 simple steps:

1. Shelf Nut
Our exclusive Buzz Feiten Tuning System¨ (BFTS) Shelf Nut moves the strings closer to the first fret according to our Patented Formula. This eliminates sharp notes at the first three frets.

: The strings are moved closer to the first fret a precise distance based on the scale length, fret width and string gauge of your guitar. The slight overhang of our nut (the 'Shelf') does this without altering your guitar in any way. So it's even fine for vintage guitars.

2. Intonation
Your guitar's bridge is adjusted according to our Patented Pitch Offsets, creating balanced intonation over the entire fingerboard - every fret - every string.
