When a guitar is refretted, careful attention must be given to the ends of the frets so there are no sharp corners and the frets feel smooth to the skin with no snagging. We pay particular attention to fret ends so there are no problems playing your guitar. We follow industry standards. We do not ball shape fret ends or apply any particular manufacturer’s shape to them. Frets are shaped to fit the radius of the edge of the fret board as well as to offer the most “real estate” and comfort when playing and bending notes.
