those pups are schaller /dimarzio so they are very hot. thats why i have switches for series/parallel which actually does something on these pups.
before these i had two 62 p bass ri in it. the bridge pup sounded like a post 1972 j pup with out the hum and maybe a little thicker on the low strings. If i were to do it again i would switch around the pups ( L sklar ) so that the part closest to the bridge would be the E A half.
