The Relentless bass pickups begin with our newly sculpted metal covers that add form and function. Although Billy Sheehan has always loved the sound of DiMarzio bass pickups, his playing style inspired him to modify the exteriors. Billy used to build them up with epoxy to round off the sharp edges. Designed with Billy, we removed all the right angled edges from a standard P Bass pair, curved the tops to match the fingerboard/string radius, and changed the mounting to a robust 1/8 circuit board that eliminates protruding mounting screws. Relentless pickups produce 50 percent more output than traditional passive pickups, and they’re drop dead quiet — with virtually no electromagnetic interference. We’ve expanded the midrange punch, adding snappy highs and precise lows. These pickups have a broad magnetic field so you can even bend notes without volume drop out. Relentless pickups will breathe new life into any bass, increase playability, and work well for any style of music from Motown to Metal. Oh yeah, and they love distortion.
