Well, I've got the guitar in my closet - a backup Squier Deluxe (i.e. red J. Mascis), and I am just kinda waiting to settle on the logistics before I pull the trigger on a sustainiac/sustainer system. It would be a JM, a tele bridge pickup with a dummy coil in the rhythm cavity to make it silent, sustainer humbucker pickup in the neck position, 3 way toggle, two switches for the sustainer, and some way to easily change batteries.
Most of this I can achieve on my own, but the battery compartment is something I'm torn about. I'd rather not do any permanent body routing. My thoughts are as follows:
1) Just keeping it hidden somewhere under the pickguard and hope that I don't have to change the battery very much
2) Cut the pickguard along the rhythm circuit so that the area covering the rhythm circuit can be separately detached without taking the whole pickguard off
3) Route between the two pickups and put a battery compartment there
FYI, someone already made a cool sustainer that I saw on Reverb a while back:

Would love to be able to find a sustainer humbucker with an off white color like that, but you kinda have to find a Fernandes guitar with one and sacrifice it. Pretty rare stuff.
