I took my action a little low and now have a problem with 1 fret which manifests with a buzz when applying the 15th fret little e string.

The 14th fret - perfect, tuner shows "e".
The 16th fret - perfect, tuner shows "#F".

The 15th fret - has buzz, sounds just like the #F on the 16th fret, and tuner is blank.

Question - under these facts, am I correct in concluding that my problem is that the 16th fret is too high, relative to the 15th?

Question - what is the cleanest way to reduce the problem fret height? Assuming I have small flat/rounded files and good sandpaper.

Thanks for any help.
