Hey i just bought new schaller p bass pups and I have some questions about installing them 1.) When I took off my old pickups from the squire affinity, i noticed that the currect pickups had a foamy material there, that my new pups dont....why dont my new pups have them, should i just take the foam off and put it on the new ones? 2.)Also, I saw that my old pups showed the pickups in series and showing the area of soldering, but my new pickups have wax or something under the pickup and I cant see where the soldering is. How am i suppose to solder and connect them this way? 3.)does it matter which pickup goes on the top left side and the bottom right? mine didnt come with any instructions 4.) how do I wire them? the factory setup only has 3 wires, while i have 4 wires with my new ones. I really really need these questions answered cause now my bass is just sitting there taken and apart and I really am clueless this is how my new pickups look like: please.
