JAZZ NECK! And then just one coil! So you get neck humbucker + 1 coil from the jazz, and bridge humbucker and 1 coil from the jazz.
The output will drop dramatically and the already bright sound of the Jazz will give you faux-quacky tones. Makes for an extremely useful tone to be honest. The phat cat needs 1k wind less and weaker magnets (degaussed alnicoV is my favorite). The only phat cat that I use, was customized as such and now, it finally works as intended, but still not a great tone, compared to the JazzN in that spot.
