I had a MM replacement neck a few years ago. Rosewood board, 1-1/2" wide nut (J width) I had to dress the edges of the fretboard (sharp edges) and it seemed like I had to adj. the truss rod EVERY time I played it (maybe cause it was BRAND NEW??) I had a similar Dimarzio neck on my Antiqua P bass years ago, never had such problems. I'd go for the Sq Affinity just for giggles & Shiites!!
