These have Alembic electronics... if I remember correctly, AXY's with Volume/Pan/Bass/Treble controls, like Epic/Excel/Orion would. They are pretty scarce, like 50-some made... I think this may even be the same one that was for sale a couple years ago. Aluminum fingerboard and a 36" XXL scale!

I think Chef Ken, the seller of this bass, used to be an active member here.
