Hello folks, i'm building a jazz bass style bass, Dimarzio Ultra Jazz pups and Aguilar OBP-3 Preamp are my 2 options for electronics, but i have some doubts in several things, so: 1) It's posible to do a: Volume - Volume - Bass/Treble Stacked - Mid/pushpull Configuration?? 2) Because Pickups are Humbuckers, it's possible to put some kind of Volume with push/pull switch build-in potentiometers? to activate the dual sound on each pickups? 3) I'd like to install a pasive tone control, so the only place available to do this is the Mid Pot, but it is already a Push/Pull pot, so the question is, theres a pot that is Stacked, and has the DPDT push/pull switch, all in one at the same time? (all this is to avoid the fact of making holes in the control plate for external switches) Thanks, as soon as i complete the bass, i will make a video and a review!
