So, over the weekend I was doing a bit of work on the neck and as I was fitting the nut I noticed how far out the radius of the nut was to the radius of the fret board. After some checking, I have measured the fretboard radius to be 20"! Don't know if this is a mistake, I know 20" radius' exist on some guitars and they are more suited to "shred" style playing. This worries me a little, I have never played such a flat fretboard. Any advice?
