Description
If your P/J bass sounds a little polite, this is the fix. The SPB-3 Quarter Pound in the P position uses quarter-inch diameter pole pieces to widen the magnetic field, which is why it pulls more low-mid punch and top-end clarity out of the string than a standard P pickup. It’s the most requested pickup in the Basslines lineup for a reason — it handles rock, funk, and everything loud without losing definition. Comes with black logo covers, a wiring diagram, and mounting screws.
Paired with it is the SJB-3B in the bridge — a true single-coil Jazz pickup wound hot, with the same quarter-inch pole pieces driving even harder attack and long sustain than the standard Hot Jazz. It’s aimed at players chasing blues grit, classic rock crunch, garage tone, or full-on metal aggression. Logo cover included.
Run together, this pair gives a P/J bass real range — thump and growl from the neck, snarl and bite from the bridge, blendable to taste. Want more tonal shaping? Seymour Duncan suggests pairing this set with an STC-2 or STC-3 Tone Circuit for onboard EQ control.
Rounding out the bundle: a set of Ernie Ball Extra Slinky Bass strings (2835), gauged .040/.060/.070/.095. Made from carefully sourced raw materials in California’s Coachella Valley, these strings deliver a bright, well-balanced voice that won’t fight with the added output from these pickups — they’ll help you hear every bit of it.
