I have a "franken" PJ bass that I want to add a series/parallel switch too. I like the idea of getting the mid/volume by running the pickups in series. I see a billion different switches on ebay. I'm assuming that a three way switch is what im looking for here. There are also a lot of different wiring diagrams to choose from. I'd appreciate if someone could link a good wiring diagram for vol/blend/tone with a swicth (if this makes any sense). I kinda like the idea of only one volume knob. I'v already googled and TB searched this, and was bombarded with a ton of ideas. I dont know too much about this mod in particular, so any kind of help would be much appreciated here. Thanks friends.
