Hey folks... I'm installing a Bartolini NTBTG-918 in a Fender Deluxe Jazz and I only have 3 knobs but need to fill 4 holes in the control plate. Since Bart has diagrams on their site for these options, I can do either an active/passive switch, or a 3 position mid switch and it's all laid out for me. My big question is, if I add the active/passive option, will I also need another pot for passive tone? Since the toggle is of the mini variety, it would be easy enough to put a passive pot in the jack hole and drill another hole for the A/P toggle. While the Bart site has a diagram for the A/P toggle, it makes no mention of a passive tone pot, but most other pre's I've looked at with an A/P option include a passive tone pot. Second, the 3 position mid switch calls for a DPTT on on on toggle switch. I can get one, but I have to order it and they are anywhere from $13 to $25. I can get a DPDT on off on switch locally for around $8. Would the DPDT switch work? It looks the same on the outside as the DPTT, but I'm clueless about the difference(s) inside. Last of all, could I just put in a simple on/off toggle in the jack position? A simple (switched) break in the hot wire from the battery to the pre so I didn't have to unplug to kill power to the preamp? Thanks in advance for any and all opinions, experiences, etc., on this. They are greatly appreciated.
