I have a regular 'ol Fender MIM Jazz Bass with an Audere preamp in it. While the 9V battery can be replaced by removing the 3-screw control plate, I'd rather just have a seperate battery box that's accessible from the back of the bass. I can take care of the routing and cable path drilling just fine, but I'm having difficulty knowing the best place to locate the battery box. Does anyone have any input on the most logical location for the battery box on the back of the bass? I'm trying to figure the location that would make the most sense in terms of a cable path and not interfering with the control cavity, etc.
