So I got the B-Ninety neck I ordered today, pretty nice. It's about the same as the neck on my Patriot ('custom' painted headstock style) except it is wider at the nut than the Patriot. Thin and fast the way I like it. Was concerned about the tuners, being the small gotoh-type, in practice they seem solid, not as good as Grover Titans, but good enough. Almost a perfect match for the body I put it on, and it plays great.
Were these necks made from a different type of wood? My Patriot's neck (an '87 I believe) is clearly maple, but the B-Ninety neck is kind of darker, more muted brownish color. Anyways I'm still waiting on a battery box to finish the project, but when I switch it to passive it sounds great. I'll post some pictures tomorrow when I have the chance, I'm quite pleased with this neck overall.
Also I think the neck is much better off with me now, judging from the paint marks on the heel, the bass this neck came off of was...HOT PINK. Ew.
