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” larger than the string. In other words, for a .046” low E string, you can usually use the .046” File and not the .050” file. 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: 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?
