Do check the tippy top of the peghead for the stamped serial number. From the looks of it, the nut needs to be reglued.
Every Alembic was made by more than one person. From the looks of it, this instrument may have been built here when Doug worked here, and if so, he certainly had a hand in its construction. But it's not accurate to identify a single person as the maker of any Alembic instrument.
I'd like to see the inside of the electronics cavity as well.
Thanks for posting!
