Hi folks,
How much different is the neck shaping on the Z models, compared to the ABII? Are they asymmetrically shaped at all? (Thinner on treble side.) If they are a bit thinner overall and smoother at the headstock, I might just have to bring forward my ABII upgrade and MTD replacement.

I'm certainly not saying there's anything wrong with the ABII neck, it's just that I've been playing my pre-Gib Tobias a lot lately and now finding the AB neck to be a tad thick.
Cheers,
EG
