My OLP bass is about to enter the next phase of modding. My goal here has always been to make the bass sound something like a robust Rickenbacker and, to that end, I've kitted it out with different pickups over time.
My next plan is to fit two Jazz-style pickups, in the virtual 24th and 36th fret locations. I plan to wire it with a 3-way switch, master volume, master tone and bass roll of control on the bridge pickup alone to give me the equivalent of the cap in older Rickenbackers. As I'm using single coils, and a 3-way switch, I'm wondering if there is any way of getting a dummy coil in to the proceedings. I have scads of cheap single coil pickups I could use for the job, once shod of their magnets. From what I gather, dummy coils have to be reverse-wound from their accompanying pickup to work. However Jazz pickups are wound in opposite directions so that they cancel hum when both turned up. Therefore does each pickup need an accompanying dummy coil, and will this kill all the high end when both pickups, and their dummies, are selected at the same time? I want to keep the bass easy to play, so I don't really want to be working with microswitches to flip the phase on the dummy coil, which is the only solution I've seen online thus far.
