When to choose it

Choose this acoustic set by the actual widths rather than the light or medium label. Compare the lowest-string file with your installed string and confirm what size the maker calls for on the other positions.

The files have two cutting edges. Measure the existing clearance and check the intended slot shape before using a cutting edge on the instrument.
