A TRUE GAME-CHANGER: Designed by our Sonoma, CA team and in collaboration with top repair techs, the Safe Zone S-File sets a new higher standard for what you should expect when you buy a Fret Crowing File. No detail is overlooked, and it is packed with unmatched features and benefits.

WHY DID I NOT THINK OF THE SAFE ZONE?: The patent pending Safe Zone innovation prevents you from overfiling. At the top of the file, there is a small strip where there are no diamonds. Once you perfectly sculpt and round both sides of the frets, the S-File stops filing and skates on top of the fret. You can hear and feel the difference and it's time to move to the next fret. It's that simple...File-Skate-Go! The premium diamonds make both fast and precision filing. Whether you are a seasoned tech or new to fret crowing it reduces the learning curve from weeks to hours.

THE PERFECT DIAMOND FILE DESIGN: The 240 premium diamond coating is perfectly rounded to closely match the original radius of your frets. One channel is for narrow/medium frets and the other is for wide/jumbo frets. After hearing many repair shops complain the wide side of existing files are too flat to use, we increased the roundness of our wide channel to improve the functionality. Additionally, our diamond file cuts in both directions, speeding up the process, unlike toothed files that cut in only one direction.

BIG IMPROVEMENT OVER EXISTING HANDLE DESIGNS: Our comfortable, heavy, ergonomic handle design makes such a big difference. It starts with our innovative blue silicone comfort grip that reduces hand fatigue. The offset design provides both added leverage when filing and allows you to clear the guitar body when filing over it. Weight makes a difference. We beefed up our design so the weight of the S-File does the work for you and is in a weight class by itself at .38 lbs (173g). Lastly, the fret size channel application is engraved in the handle so it won't rub off, allowing you to know the correct file size to use. We even include a convenient hang hole.

WORKS ON ALL FRET TYPES: It works amazing for crowning all fret material found on guitar, bass and other stringed instruments, including stainless steel. Our exclusive nose design features two lines for spot fret crowning. Position the line to be 90 degrees(straight up) from the frets and you will just be filing right where the line intersects with the fret. It's so simple but functional. Our high quality manufacturing process includes radiused & beveled edges along the entire perimeter for the comfort and safety of your fretboard.

This file is amazing! I’ve been teaching people how to properly crown files for almost 20 years, and this file shaves the learning curve from weeks to hours! It’s faster, consistent, and so easy to use!

Chris, owner and Master Guitar Tech of Third Coast Guitar (Chicago, IL), a top repair shop in the Midwest had this to say about our Diamond Coated, Safe Zone Fret Crowning File (S-File):

This file makes doing crowning work a ton easier. The crowning is the absolute most tedious and damaging to your hands of almost any other work we do, and this file takes a lot of the sting out. It will make novices better and pros more effective at this work in my opinion.

Geoff Luttrell Master Guitar Tech of Sonoma County Guitarworks and SF Guitarworks had this to say about our Fret Crowning File (S-File):

The MusicNomad S-File is a real game changer in Fret Crowning. It takes the usual learning curve from weeks or months down to a matter of hours. Unlike traditional fret files the S-File allows you to both feel and hear the change when you are finished with your Fret Crowning.

The B String Guitar Shop (Winston Salem, NC) had this to say about our Fret Crowning File (S-File):

We got 2 for our shop and our #1 tech said to “throw the other ones out “!

Walker Doubleday of Doubleday Guitars had this to say about our Fret Crowning File (S-File):

This new Fret Crowning File is a game changer!! The safe zone strip down the center of the file allows for absolutely perfect crowning each and every time. The diamond grit shapes the sides of the fret smoothly and quickly when filing in both directions with no chatter, and there is no risk of going too far! And at a price point far more attainable than some other guys, I know which one I’ll be reaching for with every fret job! Good work on this one guys!!!
