This is what Squier have to say:
Squier by Fender Pete Wentz Precision Bass Guitar
Details
The Pete Wentz Precision Bass guitar is a darkly beautiful instrument that’ll rock your face off. It’s all sleek and black and most importantly, it’s loaded with cool features like Fall Out Boy’s Pete Wentz’s own red bat/heart design on the body, plus a black bat/diamond fingerboard inlay at the 12th fret, Wentz’s signature on the back of the headstock, an eye-catching three-ply red shell pickguard and a thunderous Duncan Designed PB-105 split single-coil pickup.
