MusicNomad MN850 Diamond Coated, Safe Zone Guitar Fret Crowning File & Luthier Tool (S-File)

Another GREAT music nomad product. This is a game changer for me. Its so simple to use and virtually error proof. I used it as soon as I received in on my 90s MIJ Jackson Performer RR V. I did a spot level on 4 of the frets. This tool worked perfectly for both crowning an entire fret and spot crowning. Its also set up to knock down rough fret edges although I didnt have that issue to address.Its has some weight to it, its durable, feels high quality, and the rubber grip makes it VERY comfortable to work with. I had the crowning work done in no time. It may seem pricey at almost $100, but good tools are worth the money - not to mention the time and effort you will save using this file for your fret crowning work.Its a HIGH QUALITY tool that simplifies fret work that is critical to the playability of the instrument and costly if the fret work is not done properly. Its a MUST HAVE tool on your bench.

Perfectly, swiftly, and easily shaved the edges of the frets and took nothing off the top. Highly recommend this product.

Well designed, easy to use, does a great job. I would buy this again. Well worth the price.

Diamond Coated, Safe Zone Guitar Fret Crowning File (S-File)For context, I am a luthier of 39 years with two shops in Los Angeles County and Orange County, California.l use diamond crowning files rather than toothed crowning files for five reasons :1. They don't leave chatter marks behind like toothed files sometimes do.2. They cut quickly.3. They also work quicker on stainless steel frets than toothed files do.4. They are more durable. They last longer than toothed files because of the diamond particles imbedded in them5. Toothed files only cut in the "push" direction. Diamond files cut in both "push" and "pull" directions, making the job even faster.I picked up Music Nomad's new S-File. I like to try out new tools to see how they perform and determine if I find something better than what I currently have.I bought an S-File to compare to my Z-Files. I've been using the StewMac Z-Files for years now, and I'm a huge fan of their quality and performance.The S-File has a nice weight and balance. It feels really good in my hand. The silicone grips are especially nice and add a comfort aspect to the design. The design with the silicone grip reduces hand fatigue and cramping, associated with other crowning files.The file is 240 grit diamond coating with a narrow uncoated strip in the center. This prevents you from removing too much fret material and creating a low spot. This makes the file (dare I say?) foolproof. (The Original Z-File is 300 grit and costs $104.49. The Compact Z-Files come in 150 and 300 grits. They cost $98.99 each.)Another nice feature is that you can use the curved ends of the file to dress the fret ends with a single swipe. It removes the sharp edge of the fret end and puts in its place a nice rounded crescent edge.I did find that the design of this file made crowning the frets much faster and easier.With the Original Z-Files, you have to file on one side of the fret, then flip the file and do the other side of the fret. You also have to be very careful when filing because the corners of the Z-Files are very sharp. If you accidentally slip off the fret, you can scratch or gouge the fretboard, even through the masking tape. I modified my own Z-Files by rounding off the corners on a bench grinder and beveling the edges with a file. You don't have to worry about this with the S-File.At $79.99 vs. StewMac's Original Z-File at $104.49, it's hard to argue with the S-File's bang for the buck. However, StewMac does have a Lifetime Promise on their tools that gives them added value and longevity : "Our promise to you is simple and uncomplicated. If any of our products ever break, wear out, or fail to exceed your every expectation, simply return it for a replacement." Something to take into consideration when investing in your tools that make you money.The S-File makes crowning fast and easy with a low learning curve. Pros will appreciate the ergonomics and its time-saving design. Those just starting out will love how easy this tool makes it to achieve professional results. Both will benefit from the quality and value.I will say that the StewMac Z-File does produce a narrower contact surface which I much prefer. Although it's more work, it does give better results. The S-File's contact surface is considerably wider, compared to the Z-File. Compare the two results in the attached photos.Having had the S-File for a while now, I find that I've gone back to the Z-Files because I get a better quality job. If I have a lot of jobs to do, I use the S-File to do a quick job and move more repairs out. I still get a good result that clients are happy with.The price, quality, and results achieved with this well designed tool make it an affordable, and attractive option to the Z-Files for both pros and hobbyists.

This made quick work of crowning my frets after I used the Stew Mac fret kisser on them.

I have 3 other crowning files similar to the music nomad s file, But similar is a vague statement? The design of the music nomad s file is pretty much fool proof compared to others, it leaves a nice even crown and does not take off the top of the frets after doing a fret leveling. I literally tried fairly hard to see if I could remove some of the top using a marker on top of a fret, and what I ended up with was a very fine bead on top of the fret, after doing this I used a fret rocker to confirm that the top of the fret was level with the fret before and after the fret I just crowned using the music nomad s file and the results were absolutely even all the way across the fret, so I proceeded to crown All existing frets checking each fret after the entire neck of fret leveling was finished..? The results were every single fret remained absolutely even! Now all my fret crowning files can do an okay job, but guaranteed none except for the music nomad s file can yield perfectly even results, and I am impressed to say the least. If you have never done a fret crowning Job, by a fret leveling beam, fret rocker, maybe a fret kisser for spot leveling,(I bet music nomad will come out with a spot leveling tool soon) a fret hammer, some 1000 grit sandpaper, 2000 grit sandpaper, (#0000 steel wool optional if you don't like using sandpaper to polish out the frets) before doing a fret leveling Job remove your strings, adjust truss rod to get the neck as flat straight as possible ( use a straight edge or notched straight edge to check this)make sure all frets are properly seated using a fret hammer tapping lightly (you might use a little wood glue or some type of super glue if frets won't stay seated) check every 3 fret span using a fret rocker, painter's/ masking tape between All frets, Mark fret tops with a blue marker, take your fret leveling beam and start with maybe 300 or 500 grit adhesive strips on sanding beam, proceed with even number of strokes getting All frets, look for marking pin tops that have marking pen on top, keep working the beam until marking pen is gone off frets, check every 3 fret span with fret rocker, all should be level at this point, take the music nomad s file and match the file side to your frets narrow and tall are common on fender/squier.. but check with manufacturer for the fret wire gauge, example, narrow and tall, medium jumbo etc. Go across each fret using the music nomad s file util the grinding sound changes to smooth sound, use 1000 grit to smooth out any filing scratches, then 2000 to get some shine, use some frine fret Polish, wipe off, remove masking tape, use some fretboard conditioner like f-one wipe off, restring and retune and your guitar will play as smooth as butter. There are some good YouTube videos by music nomad for all this and more... But the music nomad s file is simply unbeatable and fail proof, which Will give even beginners the confidence to go forward and giving there guitar a custom shop feel and optimum playability, intonation, and buttery smooth bends and playing in general..

This is a great tool.Its the easiest crowing file I have used.Well worth the money.The diamond cuts well.Just keep it clean .

Almost fool proof

La mejor herramienta para coronar

I was sceptical about the price for a file but after using it I think it is brilliant. Really works fast and I have discovered it works great at rounding off the fret ends. Nice product.

This is a great fret file. It took me about 10 minutes to crowd my stainless steel frets after a levelled them. It's a bit pricey but not as pricey as some of the other big name files out there. It's very comfortable in the hand too. As far as I can tell, this is the perfect file for people wanting to maintain their guitars. Of course the proof of longevity is in the hands of luthiers who are filing frets more often than once every couple of years!

It's unfortunate Music Nomad tools are super expensive in Canada (curse the exchange rate and shipping costs from USA) . Had a total fret board to do, so had to bite the bullet and purchase the tool. It works, does not damage the fret board. If you use it as described in their videos you can't miss it up. Using this tool minimizes the human error factor, its basically fool proof. It saved time, only hours to use vs. days by other methods. It is a quality tool and highly recommended. I don't believe there is anything else available that would do as good a job for what I needed to do.

Very good fret file. Easy and comfortable silicone cushioned handle, good angle to use without removing the guitar neck and good size fit for both wide and narrow frets. Sendible design failsafe to avoid removing too much from the upper crown. Like it!
