JB Jr.™ Strat Pickup | Seymour Duncan (2024)

We recommend buying the set.

We've been making great pickups for over 45 years. The JB Jr.™ Strat pickup sounds great alone, but sometimes one pickup is not enough. If you don't know where to start, we recommend getting the set - it captures the full voicing of what we tried to create, as well as ensures it won't be out of phase with other pickups in your guitar.

TECH SPECS

DCR – Short for DC Resistance, is measured in Ohms and is the total resistance of the copper wire wound around a coil form. The length of the coil form, the number of turns and the gauge of wire all affect the DCR reading. DCR is often used as a gauge of output because as the turns increase, so does the output, though magnet type and the coil geometry also influence output.
Magnet – We use several different magnet formulations: Alnico 2, Alnico 3, Alnico 4, Alnico 5, Alnico 6, Alnico 8 and Ceramic 5/8. In the case of pickups, the most significant characteristic is the gauss strength, which is a measure of the density of the magnetic field. Of the magnets we use, Alnico 3 has the lowest gauss strength. From there in order of ascending strength you have A2, A4, A5, A6, Ceramic and A8. As the gauss strength goes up, so does the output. The magnets at the lower end of the scale tend to produce a softer attack and a degree of “bloom” to the envelope of the note.Ceramic magnets should be considered as an individual case because they do not contain any nickel or iron. This has the effect of decreasing the inductance of the pickup and significantly raising the resonant frequency. It is for this reason that many consider ceramic magnets to have a brittle sound, not their gauss strength. Looking at this from another point of view, ceramic magnets can be said to produce increased clarity, better note definition and faster response to picking.
Output – The overall output of a passive pickup is influenced by several design factors: number of turns of wire on the coil(s), strength of the magnet, coil geometry and magnetic circuit geometry.The output of an active pickup is influenced by the same factors but is predominantly determined by the design of the onboard preamp.

Description

The JB Jr. model will take your Strat to a whole new level. In the bridge position, this high output single coil sized humbucker will give you nice crunchy chords and screaming lead tone with that classic upper midrange cut. There will be tons of bright harmonic sparkle, and a tight focused low end.

In the neck position of your Strat, the JB Jr. will deliver a big, bold sound. Great for fat rhythm playing, or thick, searing solos, this pickup packs quite a punch. The 4-conductor lead wire gives you access to parallel and split wiring options for added versatility. This pickup is a drop-in for any single coil pickup route.

Hand built in Santa Barbara, CA, the JB Jr. for Strat pickups come with a ceramic magnet, 4-conductor lead wire for multiple wiring options and are wax potted for squeal free operation.

Neck/Middle position models will have the same output, wind direction and magnetic polarity.

Position
STRAT POSITION INFO (not all of these are available on every product family):- Neck/Middle/Bridge position models will have the same output, wind direction and magnetic polarity.- Middle RwRP position (reverse wind/reverse polarity) – choose this to have a pickup that will be hum-cancelling with one of our neck or bridge models. - All sets, except the Jimi Hendrix signature model, come with a Middle RWRP as the Middle Pickup.- Left- for some models with vintage staggered pole pieces, we offer a left-handed option. The stagger will be reversed for left-handed players.- Tapped- High output models may have a “tap” option available. An additional lead wire is placed midway through the coil wind, allowing wiring to a push-pull pot or mini-toggle switch to give an additional vintage output level option.
