Hi Ryan.
The Ebony neck laminates in Alembic instruments are continuous pieces of wood for the entire neck. They are NOT spliced together. Alembic doesn't splice together ANY neck laminates. Now the necks ARE cut at a diagonal angle at the peghead, and then the peghead is turned around at a 14 degree angle, and glued back on. This is to increase strength, and make it easier to repair broken pegheads when they occur. But the actual portion of laminates that runs from the nut to the tailpiece/end section of the instrument are continueous pieces of wood.
The ebony is NOT tinted. The black color is the natural color. My custom 8-String Europa has 6 Ebony laminates in the neck. While they are mostly black, there are naturally occuring small brown/caramel colored sections. They are pretty, part of the natural beauty of the wood, and I don't mind them.
You can see my bass' COTM thread through this link:
http://www.alembic.com/info/8string.html Further, if you go to the (Alembic) main page, click on Alembic Club (which you do to read/post here) and go to Alembic Basses and Guitar (instead of Miscellaneous -where you're at now) and scroll down and open up the Cool Necks! thread, you can see a pretty good close up of my 8-Strings' neck, and also of Rami's Dark Prince -which has a neck made completely of Ebony and Purpleheart. If you go to Factory to Customer and look up Mark's Custom 6-String Bass you can see my custom in progress, which has a center Ebony laminate. And if you use the Search function -look for it at the bottom of the page, and type in Ebony Neck Laminates that might help you find others.
Actually, a significant portion of the new customs in the Factory To Customer section and also a significant portion of the newer Custom of the Months in the Custom Archives (including this month's COTM) have Ebony neck laminates. Dig around and you'll find a lot of them.
They look great, and sound great. The effect on the alreadly awesome sound of Alembics has to be heard and experienced to be believed and appreciated.
