Take your Precision Bass® to the next level. DiMarzio’s Relentless P™ steps beyond the traditional P-Bass® sound and can only be described as massive. It has more of everything: more volume, beefier lows, a growling midrange, and crispy highs with better individual string definition. DiMarzio kept the same expanded magnetic field that they invented for the DiMarzio Model P® in 1977, improving the frequency response by adding body to the notes and delivering a fat, punchy tone.

The new cover shape, designed with Billy Sheehan, includes all the comfort improvements DiMarzio made to the Relentless™ pickups. They've 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-inch circuit board that eliminates protruding mounting screws. DiMarzio’s passive hum-cancelling two-piece pickup design produces 50 percent more output than traditional passive pickups, and they’re drop dead quiet — with virtually no electromagnetic interference.

To dial in (or fine tune) the individual string output, the Relentless P™ includes eight adjustable pole pieces. Each pickup is fully potted and includes DiMarzio’s new metal covers and foil-shielded hookup wires, dramatically reducing other types of stage noise. All Relentless P™ pickups are handmade in the USA, tested, and matched for quality control.
