Just got the bass!
Some crappier pics attached. Am busy trying it out.
The neck is unbelievably comfortable to play. It's easy to reach anywhere on the fretboard and the fretting feels "light" for lack of a better word.
From what I'm feeling, it's a pretty shallow C profile with a nice round edge. The neck is wider than a typical G&L neck though, but it's hard to tell.
The vintage frets and 9.5 radius I think worked out perfectly. I know some people can't tell, but for whatever reason the extra "wood feel" and curve in my fingers helps me play with a lighter touch. I can't put my finger on it! Bum ta tiss.
The closest neck to this one that I've felt before was on the Road Worn P bass from Fender. That's the 1.75" nut, 7.5" radius, C profile neck with vintage frets.
