Mike Lull's Guitar Works is proud to be an authorized retro fitter of the Buzz Feiten Tuning System for guitars and basses. Acoustic and electric guitars can now be retrofitted with this revolutionary system.

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 moving the existing nut or using an exclusive Shelf Nut branded with the Feiten lightning-bolt logo for authenticity. Installation of the Shelf Nut is non-invasive to your instrument. This is great for vintage instruments.

Nut placement is calculated using a patented formula for your guitar based on its scale length, string gauge and fret width.

Step 2: Your guitar is intonated according to 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.

Your guitar will sound more pleasing to your ear. The beauty of having a guitar that is truly in tune and properly intonated with the Buzz Feiten Tuning System is that you can focus on your technique and expression rather than being distracted by the tuning inconsistencies inherent with standard intonation.
