Hi Rocky; welcome to the board!
A mystery bass!!
To add to the above discussion, the pickups don't look right. No adjustment screws; unusual shape.
I'm thinking we've seen a similarly shaped omega cut once before.
The bridge looks post '76, except the plating makes it look newer than that.
Conceivably, if it were a Series, the humx could be hidden. There were also, if I remember correctly, a very few Series with no humx. However, this bass only has one switch; so I'm thinking it's probably a stereo/mono switch and that there are no Q switches.
Does it have one truss rod or two?
I'm wondering if it's an employee project.
