Hi, I've made the Stingray style bass and I've recently upgraded it by wiring in a switch that allows me to switch the pickups from parallel wiring, to bridge single coil, to series wiring. I used this wiring diagram: https://guitarelectronics.com/1-humb...outh-parallel/
It works in that I get three different tones. However, when I go to the single coil mode (centre switch) and tap on the pickup poles with a piece of metal I hear a loud noise from the bridge-side magnets, but also a faint noise from the neck-side magnets too. Shouldn't the neck-side magnets be completely silent if this is single coil? Have I messed something up in the wiring do you think? Incidentally, when I do go to the 'single coil' mode, there is no humming, so I'm still getting the clean humbucker sound, and it sounds thinner and more trebly than the other tones but with same volume as the parallel mode (series is loudest and most bassy). Is this the way it should be or should I rewire? Thanks for your help.
