I posted this on another forum out of curiosity.
Do any of you file down the upper frets on your guitars, from the twelth fret up to the top fret?
I have always done this to make these high notes easier to play in the likes of Shads music and other tunes too.
I have always found that lots of guitars are almost unplayable up top, especially my Squier Bullet, I had to do a lot of work on that to get it to my satisfaction.
I'm guessing that manufacturers do not think that these frets are used that much by most guitarists and dont spend too much time on them.
