Hey look at that. That's the right headstock but a different logo. We're definitely getting closer! And they do call it a Crue model.
Now that I've removed both pickups, the bridge is a SD Custom Duncan. It says so on the base plate. I assumed the neck was too, but no. The neck is the California pickup. So it's original.
It has really nice Grover tuners on it too. I assume those came with it?
If anyone has an idea what the bridge route might be for I'm all ears. Thanks again everyone.
Got any more pics of the route? Any extra screw holes? Is there any original paint inside to give an idea what was original cavity and what was routed for the new vibrato? I'd tend to guess that, if it was a hardtail originally, there'd be filled stud holes outside the footprint of the aftermarket vibrato, but I might be underestimating how wide it is.
