DiMarzio Model PJ™ pickups reproduce the warmth and roundness of the traditional Fender® Jazz Bass® sound with increased power and hum-cancellation. The additional power translates into a bigger sound that emphasizes the resonant character of the instrument. The DiMarzio Model PJ™ pickup’s sensitivity and deep tone are also the perfect complement to fretless basses. Double-stop glissandos and delicate violin-style vibrato speak with a classic, woody voice simply by backing off slightly on the tone control. This set combines the classic combination of the DiMarzio Model J™ with a DiMarzio Model P® pickup in one drop in set.
