Large ¼”diameter alnico 5 rod magnets and a high output coil wind deliver the most tone and attitude you could ever want in a 5-string P-Bass pickup. The quarter-inch diameter pole pieces expand the magnetic field and extend the frequency ranges for fat, full, punchy sound with tremendous mid-range presence and maximum output, giving your low B string more oomph and presence than ever before.

This Precision pickup is for musicians who want maximum output and extended frequency range.

The Seymourized ™ design balances the coils with the magnets for great sustain and harmonics. High output with lots of clarity and high-end punch.

Dimensions: Length = 2.25"(57.15mm) Width = 1.09"(27.7mm)

QP-PJ 4 String PJ Set

Excellent pickups
By The Maiden Priest
Love these pickups. I put them (P/J 1/4 pound set) on my '70s Kramer and it rocks! Classic metal like Priest and Maiden is my genre of preference, and am totally happy with these pickups for that style.

A truly impressive pickup
By Ed Tapper
I have used SD Jazz pickups before, albeit in a passive bass (namely the 67-70mm pickups). I have to admit that I was skeptical of the Quarter Pounder, mostly due to their advertized high output and overwound coils; worried that they'd be louder than the MM-style pickup that was also in the bass. I was pleasantly surprised that the output is the same and the pickup has a great aggressive tone. Lots of growl in the low end with clean highs. I would recommend this pickup to anyone.

P/J QP setup
By Daniel
I am hoping to get a handle on these - great output, balanced tonal response, but paired with the Bartolini 4.5 A/P I feel there's a lack of warmth. I will certainly continue to futz around with these, which I have in a P/J setup on an 80s Fender Jazz Special, but I suspect that these pups would be at their best with a simple passive setup - perhaps with a pair of Tonestylers.

The Duncan SJB-3b Quarter Pound Jazz Bridge pickup works great with the Quarter Pound P pickup. They are both installed on a bass I put together---passive "old school" with a swamp ash body. It sits great in the mix. Both pickups are great all around performers!

Bought the SD Bridge and Neck pickups and what an upgrade from stock!
Full fat sound,beautifully refined deep bass tones right through the mids and at the top notes. With these on my Fender Jazz Bass It has lifted the instrument to another class. Simply cannot believe how bad the stock pickups were, and now even the tone controls seem to have better balance.

P/J QP setup
By Daniel
A good overall pup - good output, balanced response, but I don't get a good sense of character with the preamp I have it wired through, a Bartolini 4.5 AP and as such I don't feel that I can provide a great review. I get the sense that these would really growl in a passive setup, but I can't recommend including them in a A/P setup.
