Jackson 2919004586 JS2P 4-String Electric Bass

The Jackson JS Series Spectra Bass JS2P is a right-handed, 4-string electric bass built for players seeking a modern-feeling instrument with flexible onboard controls. Its 34-inch scale length and 24-fret layout provide the familiar reach and range expected from a full-scale bass. The Blue Burst finish pairs with black hardware for a distinctive stage-ready appearance.

A poplar body forms the foundation of the JS2P, while its poplar burl top adds a figured visual layer. The offset Spectra Bass body shape includes a large upper horn designed to help distribute the instrument's weight. This construction is suited to practice, rehearsals, recording, and live bass setups.

The bolt-on maple neck uses a scarf-joint construction and a satin finish. Its 12-inch-radius laurel fingerboard, jumbo frets, and Speed Neck contour are designed for direct, comfortable movement across the neck. White dot position inlays and side dots provide clear visual reference points.

Jackson equips the JS2P with a P/J pickup arrangement: a P-Style pickup at the neck and a J-Style pickup at the bridge. The volume, blend, and bass-boost controls allow players to combine the pickups and adjust low-frequency emphasis. A push/pull function in the volume control selects active or passive operation, providing an option to bypass the active circuit.

The JS2P uses a Jackson hardtail bridge, sealed die-cast tuning machines, and nickel-plated steel .045-.105 strings. These components make it a practical fit for a standard bass amplifier and instrument-cable setup. It can also serve as a versatile second bass for players who want P/J pickup voicing and active/passive control options.

Design & Installation

The Spectra Bass body is made from poplar with a gloss finish and poplar burl top. A bolt-on maple neck with scarf joint, satin neck finish, laurel fingerboard, black plastic nut, black hardware, and a unique Jackson 2x2 headstock complete the design. The instrument uses a Jackson hardtail bridge, black pickup covers, dome-style knobs, and standard strap buttons.

For amplified use, connect the bass to compatible bass amplification with appropriate instrument cabling selected separately. The factory string set is nickel-plated steel in .045-.105 gauges, and the instrument includes a saddle-height wrench and truss-rod wrench for setup adjustments. Use the blend control to balance the two pickups, then choose active or passive operation with the push/pull volume control.
