Hello! I am currently working on a tri-pickup bass project, I have a Seymour Duncan ricky pickup sandwiched by two guild bi-sonics (guild - neck, SD ricky - middle, guild - bridge). I plan on wiring it with a volume & tone for each pickup, 3 individual on/off switches for each pickup and a master volume (500k pots all around). I figured i could wire each pickup like a p-bass then send it through the switches and have everything meet at the master volume, would it work like that? Can i do it entirely passively?
