DiMarzio introduced the
world’s first Fender Jazz bass replacement pickups at the NAMM show of
1977. DiMarzio invented the dual bar ceramic magnet structure for extra
power and included twin hum-cancelling coils for decreased noise. The
DiMarzio Model J is 50 percent quieter than the original Fender Jazz
bass single coil pickups, and it's 60 percent louder.
We also
added adjustable pole pieces to improve the string balance and designed
them in our signature cream color. At its introduction, the DiMarzio
Model J immediately become an industry standard and has been the pickup
of choice on thousands of hit recordings.
With the introduction
of the Relentless P bass pickups, co-designed with Billy Sheehan, we
began to think how we could make our Jazz Bass pickup even better.
As
with the Relentless pickups, we removed all the hard edges from the
standard J Bass pickup and added an arch to the top of the pickup to
bring the sensing coils and pole pieces closer to the strings. These
improvements increase the dynamic range and make active circuits
unnecessary.
We invented (patent pending) parallelogram-shaped
coils to add dimension, punch, and dynamics to the Relentless™ J sound,
and we incorporated metal covers with foil-shielded cables to further
suppress the background noise.
DiMarzio’s extra shielding makes
the Relentless J better for both recording and stage performances. We
mounted it onto a robust .09375” thick circuit board base plate so we
could eliminate the annoying protruding mounting screws - ultimately
creating a more comfortable and consistent foundation to rest your
fingers on.
To improve the balance when both pickups are used
together, we made the bridge position pickup louder than the neck
position pickup. When the pickups are blended, you get a better volume
match.
The Relentless pickups incorporate Neodymium magnets and
produce 70 percent more output than traditional passive pickups, and
they’re dead quiet. We’ve expanded the mid-range 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 J
pickups will breathe new life into any bass, increase playability, and
work well for any style of music from Motown to metal.
DiMarzio's Jazz Bass
pickups are sized as a direct replacement for USA made Fender basses.
Other basses such as Squire, G&L, PRS, etc. may require the use of a
neck-sized pickup in the bridge position, or modifications to
the bass. Please check the dimensions of our pickups here, and compare
them to the dimensions of your bass to ensure proper fit before
ordering.
