When it’s to thump on the low-end side, Mitchell-Cárdenas grabs this Frankenstein Fender that has a 1978 P-bass neck put onto a 1976 P-bass body. His best friend growing up gave him a 1978 P bass as a high school graduation present. He was having problems with the body so he ditched it and kept the ’78 neck for a rainy day. A few years ago he came across a ’76 fretless P bass that he couldn’t pass up and one day it struck him to combine the best parts of both basses. He’s since used it on the last three Mutemath albums—Armistice, Odd Soul, and Vitals.
