I am in the final stages of a swamp ash Jazzmaster body build. It will have a Duncan designed humbucker in the bridge position and a GFS Mean 90 (P90) in the neck. Now it's down to the neck. I am currently planning on a maple neck with either a rosewood or pau ferro fret board. As I am a thumb and finger picker (rarely if ever use a pick), any thoughts as to which wood would be the better choice for smooth, clear tones?
