Today I fixed the paving.
Rubber mallet in hand... took it as a sign... I’m going to give those frets a tap! Once I attacked the half dozen frets sitting high, I decided all of them would benefit from a little gentle persuasion. Looking at the neck I’m happy I did it. Frets appear to be sitting better and got some practical use out of those old text books. Looking forward to the arrival of my sanding block.
