Q: What is the general rule for what size file I need for a certain string size?

A: The general rule is that the file should be the same size as the string, up to no more than .003" - .004" larger than the string. In other words, for a .026" string you would use the .028" file; for .011" string you use the .013" file; for the .052" string you use the .056" file and so on. If you go much larger, the slot can become so large that the string vibrates in the slot, causing a buzz. If you use a file smaller than the string, the slot will be too tight, causing tuning issues.

 

Q: I’ve noticed the nut material clogging up the diamond file and it feels dull and is not cutting as well. How do I clean the blade?

A: Using a stiff bristle brush along with a mixture of mild soap and water will clean the files. Dry the blade after cleaning. 

 

Q: Are there replacement blades to buy?

A: The majority of the cost is in the diamond coated blade and they should last a lifetime for most people so we do not sell replacement diamond coated blades.

 

Q: I am buying 6 files that are not in a recommenced set, can I get one of those nice gold cases?

A: We are sorry but we are unable to manage custom packs like that, and only sell the gold cases with the part numbers that show it comes with.

 

Q: I noticed on the smaller nut file sizes that are 300 grit such as .013”, .017 don’t cut as fast as the 150 grit nut files. Why is that?

A: The Nut File sizes .010-.024 were designed with a finer 300 grit compared to 150 grit found on Nut File sizes .028” and up. The higher 300 grit will not cut as fast as 150 grit which is great when cutting narrow nut slots (high E, B)  to avoid over cutting or chipping and ensuring the smoothest, roundest nut slot every time. Slow and steady when cutting Nut Slots is the safest way to cut them. 

 

Q: I filed my nut slot with the proper size nut file, and it is still a bit tight in the slot and pings when tuning. What should I do?

A: You're in luck. We have a video showing a technique called rolling the file that can help solve your issue. https://youtu.be/atzYl-TlIZA

You would roll the file slightly to the right and put a bit of pressure going down the left wall of the nut slot and stop when you get to the bottom of the slot as to not go any lower. You would then roll the file slightly to the left and put a bit of pressure going down the right wall of the nut slot and stop when you get to the bottom of the slot as to not go any lower. It's important you do not want to open the slot too much or make the slot lower. You can also use MusicNomad's Tune It in the nut slots as a lubricant. 

 

Q: I have a set of nut files that do not fit my exact string sizes. What do I do?

A: The general rule is that the file should be the same size as the string, up to no more than .003" - .004" larger than the string. Our files sizes and sets are designed to accommodate all string sizes and stay within the .003" - .004" tolerance. If you go much larger, the slot can become so large that the string vibrates in the slot, causing a buzz. If you use a file smaller than the string, the slot will be too tight, causing tuning issues.

 

Q: I play a set of electric guitar strings .010" - .046". There is a .028" for the D string and not a .026" file. What do I do?

A: The general rule is that the file should be the same size as the string, up to no more than .003" - .004" larger than the string. Our files sizes are designed to accommodate all string sizes and custom sets to stay within the .003" - .004" tolerance. The .028" file is well within the tolerance for the .026" string. If you go much larger, the slot can become so large that the string vibrates in the slot, causing a buzz. If you use a file smaller than the string, the slot will be too tight, causing tuning issues.
