We were asked recently how we got frets to look so good. There a few methods to get to the same result. Here are a couple. One way is to use small fret polishing wheels that we shape to the contour of the frets and use different grits to bring the fret up to a slick feeling polish. The large wheel works great to polish the frets and the fingerboard. The goal is a smooth and slick bending fret and have the fingerboard not feel sticky under your fingers.
I wish I owned one of those polishing machines! Maybe I’ll invest in something soon.
It is nice to have for sure!!
