Fun problem indeed!Thx - I absolutely loved the AB-1 neck I had years ago, and Sheldon was saying in a video AMA that the Z is maybe a millimeter thinner front to back. I have a build slot in but have yet to verify what the build will be. Vascillating between Sklar, tricked-out AB, or a more plainclothes Z. Fun problem to have!
the neck specs are all listed on the website for technical comparisons.
There honestly is quite a different “feeling” to them thou. I wouldn’t call it subtle
my biggest beef(only beef)with the 5 string Z neck was my tendency to pull the G string off the neck up around the 12th. I had to be conscious of my technique to avoid it. That said, on the six string that doesn’t happen anymore.
and that Beff was definitely technique related, not bass related.
