So I have This junk bass I've been messing with lately. It has 3 pups. I wired it v/v/v/t. When I plugged it in, this is what happens: when the tone pot is rolled off, everything is extremely quiet. When the tone pot is rolled on, the tone is on, but the volume as a whole gets really loud. What have I done wrong? Or do I need to put up a diagram of exactly how I wired it?
