Alright, so eventually every guitar needs its frets replaced. The ‘Nib’ presents a problem in that the only way to replace the frets is to precisely measure each fret and install (which I’ve done and its very very expensive). I usually try and talk the client out of it for the following reasons.
1. The fret never goes in exact and filling is required.
2. The fingerboard is prone to seasonal changes. When it expands It leaves gaps where the string catches and cracks in binding when the board shrinks.
But Most important!
3. Sometimes doing a refret is the best solution to numerous issues that come from seasonal changes. Planning a fretboard and giving it a fresh start is sometimes the only way to remove warps and inconsistencies in the fingerboard. Leaving the nibs in place makes it almost impossible to do it properly.
4, It’s just a lot cheaper.
