Warranty for Fret Maestro:
- At our sole discretion we may exchange all or part of the product due to factory defect(s). Determination of what constitutes factory defect(s) is solely at our discretion.
- Clogged Files: We do not replace or exchange or in any manner compensate for clogged files. Determination of a clogged file is solely at our discretion.
- All sales are final.
NOTE: Improper use of a diamond file can lead to clogging the file, making the file behave like a dull file. Using a diamond file to file fret wire requires following the rules: See the rules here:
Proper use of Diamond Files
Fret material will not chip diamond grit.
Fret material is much softer than diamond, so it will clog a file if the file is pressed to a fret.
Proper use is to let the weight of the file do the work without pressing down.
Clog Preventative trick: Dry Silicon Spray treat the file.
Clean the file: Use a Belt sander Eraser. Do not jam the eraser into the file, use it lightly so it can grab the filings instead of pressing them into the diamond.
Best Practice: Treat the file with dry silicon, a light application, not heavy... and use the belt sander eraser as you work, giving the file an occasional erase. Let the weight of the file do the work.
If a file becomes completely clogged... we offer replacement files at a very fair price for verified customers. We will verify that you purchased from us the FretMaestro that matches the replacement file you order, otherwise we will decline.
Dry silicon spray, and belt sander erasers are readily available online or at hardware/tool/home improvement stores.
