I'm considering having a Sadowsky pre installed in my early-70s Fender Jazz. I've got an email into Roger and he's usually very good with replies, but thought I'd get some feedback from you folks, as well. I'd like to retain the modified wiring that is currently in the bass, which involves a push-pull pot that allows me to do "all-bypass", has a rotary pickup selector instead of dual volumes, etc. A big concern I have is space... i.e. where would I put the preamp board + battery in the small Fender Jazz control cavity? What have you guys done? I assume nobody else is in the same *exact* situation of having a couple of push-pull pots and a rotary pickup selector taking up space in their Jazz, but where'd you place the preamp board + battery? Did you rout the control cavity deeper? Rout a small cavity under the pickguard? Rout a small cavity close to the bridge and add a battery box? Thanks!
