Squier Vintage Modified Jaguar Bass Body Routing

I've done some Googling and can't find an answer to what seems (to me) to be a pretty simple question: is the Squier Vintage Modified Jaguar Bass with the single active H pickup routed only for that pickup, or is there additional routing under the pickguard? I'd love to modify one for an HH setup, but I don't have the tools for a DIY routing job.

The only other solidbodies with an HH setup that I can think of are Epiphones with mudbuckers (not nuts about that sound, but would've been all over the Embassy if they'd done that as a 30" instead of 34"), or the Squier Rascal, but I hate the bridge placement on that, and the fact that it makes the neck feel more like a full-scale than short-scale. If you can think of anything in the sub-$500 range, I'm open to suggestions there, too.
