Hi guys, I've got a Seymour Duncan STC-2P preamp that I'm trying to install in a Mexican Jazz Bass, but there's no way the whole thing's going to fit in the original cavity!
I've resigned myself to having to route a new cavity in the back for the battery, but even then the circuit board and all the wires won't go in the original cavity.

Has anyone got any experience with this same set up please? I'm desperate for ideas if anyone's got anything they can share pleeeease!!
Apologies if this has already been discussed, but I couldn't find anything in the search.
 
I've always had to route space for the battery...either under the pickguard or in the back.
