Buzz Feiten Tuning System

Authorized retro-fitter for the Buzz Feiten Tuning System. The tuning and intonation setup for your bridge saddles, along with the professionally installed shelf nut, brings the guitar into proper intonation that is in tune all over the fingerboard. Play in tune from the first fret to last. Non-invasive Retrofit does not change your guitar in any way.

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 Systemยจ (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.
