DiMarzio Model J™ 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 J™ 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. For an even more varied choice of tones, pair a bridge position DiMarzio Model J™ with a DiMarzio Model P® pickup. The warm, fat tone of the DiMarzio Model P® plus the tight punch of the DiMarzio Model J™ open up the sound of any bass.
Unlike traditional Js, each Model J™ is individually humbucking. It's not a stack: each coil picks up one pair of strings. By doing it this way, we keep the resistance down, and the tone clean and clear.
