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.

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..

I`ve only use this one time but it worked good and got the job done. Reasonably priced

Well this just makes crowning disgustingly easy. Very easy to use. I had NO experience and couldn't be happier. Saw Philip McKnight demonstrate and said that's exactly what I need. Nothing bad about this tool. If you do any work on your axe it's a must have tool. Accurate, functional, quality and easy on the hands. Love you can hear when you're crowned. Not really much of a learning curve. Basic knowledge will do. It did for me. Doesn't damage and I didn't use tape. Comfortable fit for anyone. Nice rubber coating and sizes that won't wear off. Forget the old files, this is the future.

Great product, love the ergonomics and the safety groove . Makes this file a no-brainer. If you're going to do fret work you need this. It worked great on stainless frets but we'll see what the longevity is as this was its first job . I have other diamond files to compare to but the safety groove takes it over the top.

Great quality product and works as described. Some constructive criticism. I wish is was a slightly finer grit.

I'm what I call an amateur luthier, meaning I work on guitars my own guitars because I find it fun and I think I'm saving money. Of course, I have a bunch of tools that I've acquired as needs arose, so this little hobby of mine has actually cost me money! Anyway, I was really reluctant to spend the money on this file. It's expensive. But I found myself with an old Squier Strat with some fret wear that needed to be leveled. After sanding the fret tops it was unavoidable. I needed to crown them. I ordered this file and when it arrived, I did just that... in minutes... and nicely. (Don't get too excited. I still had to sand and polish them.) I have watched many videos of luthiers using many different techniques. My conclusion was that at my skill level and despite the cost, this was the file I had to buy; the only file I should buy. There is not an easier, faster, safer way to crown a fret. I haven't been in the game long, but this is a game changer. This makes one of the most intimidating tasks - working on your own frets instead of paying someone else - not only less intimidating, but easy. It makes it almost fun and it is definitely satisfying to string up the guitar and say, yup, nice job.. There are a lot of things I'm learning over time by making mistakes, but buying this file eliminated who knows how many mistakes I would make using more traditional tools to crown frets. Someday I will refret a guitar, but I won't be doing it because I screwed up the crowning.
