The Katana Fret-level System

A fret-level is is a process whereby a guitar tech or luthier, removes the strings from the neck of a guitar and and sands across the entire neck, usually with a sanding block to attempt to achieve the leveling of the frets. Sounds good in theory. The problem comes in when the guitar is re-strung and brought up to tension. Of course the neck starts to move, as it's supposed to, into its very slight upward bow. The strings are tuned and when the guitar is buzzes in certain locations. For most luthiers or guitar techs, this is standard practice, they then remove the strings and try again. They get pretty close but they never quite achieve a perfect fret level. Why?

The answer is rather simple. The standard fret-leveling procedure as described above does not take into account the final curve of the neck at tension, when its being played. 

The solution: The Katana Fret-Level System. The Katana system allows a guitar tech to leave the strings on, at tension and the guitar tuned up to play. The Katana tool is positioned on the neck and adjusted to match the curve of the neck. Its then further positioned between the strings utilizing its clever design and the guitar tech begins their sanding of the frets. Once the sanding is complete and prior to any fret dressing that is needed, the guitar tech can play the guitar, as is, to see if they've sanded enough to eliminate and high or uneven frets.

The results that we've achieved on our Fretlight guitars in a very short amount of time has been remarkable. This Katana method is a far superior method and technique for achieving a great playing guitar. We highly recommend that all of our customers choose this option when ordering their Fretlight guitar.

PLEASE NOTE: All of our electrics are set-up with 10 gauge strings (10-46) and our acoustics are set-up with light gauge strings (11-52). If you change your strings to a different gauge after you receive a guitar that has had a Katana Fret-Level, the playability may be affected (this is true of any fret-level). So if you KNOW you're going to change the strings to a different gauge when you get your Fretlight, we recommend NOT opting for the Katana Fret-Level.
