Explanation of a Compound Radius fretboard and how it impacts on pickups.

It must be understood that the radius formed by the strings on a Compound Radius fretboard continues to flatten towards the bridge. We call this the projected radii.
As you can see in the diagram below, a 10” radius at the nut and 16” radius at the end of the neck projects to a 20”radius at the bridge. The section between the end of the neck and the bridge is called the pickup zone and the radius range there is between 16” to 20”. The radius range of our Flat magnet stagger is 14” to 20” and that covers every different radius found in the pickup zone.
At bottom is an example of a typical uniform radius fretboard (some being … vintage Fender 7-1/4”; modern Fender 9-1/2”, Gibson 11”; various other brands are probably different.
