I have a yamaha bb4nf, The bass plays well, I'm just not into fretless. I was thinking about swapping out a new fretted neck, one small problem. The yahama neck is 24 fret, and about an inch longer than a fender style neck. Has anyone come across a 24 fret deeper pocket neck anywhere? Every thing i've seen for replacements have been fender size/style 21-22 fret necks. Any help on this would be great, I hate having a bass lying around without a neck on it.
