Hi, I just bought a set of what the seller told me to be, vintage noiseless pickups, I'm changing the ceramics in my 2015 CAR RW fender mim. I don't do that myself yet, so i'm taking them to the tech... Doing some research I found that they look identical, at least to me, to the hot noiseless. Same pole's height, same wiring, and all. I want to know if there is a way to tell which type are they, before I install them...I know I'll hear the difference right away once instaled, but I wanna know before and I don't have a multimeter.
