    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.

    The Buzz Feiten Tuning System® Authorized Retrofit involves two steps:

    Step 1: The nut is moved closer to the first fret to eliminate sharpness at the first three frets caused by end tension. This step employs our exclusive Shelf Nut which is machined from high quality bone. Installation of this part is non-invasive to your instrument. Your Authorized Retrofitter removes the original nut and installs our Shelf Nut according to our patented formulas for your guitar based on its scale length, string gauge and fret width.

    Step 2: Your guitar is intonated according to our patented pitch offset formulas. This step uses the existing adjustable bridge saddles on your guitar bringing each string into pleasing intonation with every other string at every fret across the entire fingerboard.

    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.
