Jackson 2919004585 JS2P 4-String Electric Bass

The Jackson JS Series Spectra Bass JS2P is a 4-string electric bass built for players who want a versatile, full-scale instrument with flexible active and passive operation. Its PJ pickup layout covers defined low-end support, punchy attack, and a broad range of blended tones without requiring a complicated control layout. The Black Burst finish, poplar burl top, and black hardware give it a distinctive stage-ready appearance.

This bass suits beginners seeking a capable first instrument as well as experienced players needing an affordable secondary bass for rehearsals, recordings, or live use. The offset Spectra Bass body shape and large upper horn are designed to distribute weight evenly and help reduce neck dive. A 34-inch scale length provides the familiar feel and string tension used by many standard electric bass designs.

A Jackson P-Style neck pickup and J-Style bridge pickup provide the core voice of the JS2P. The neck pickup supports rounded foundational bass tones, while the bridge pickup adds focused definition and growl. A blend control lets players combine the two pickup voices to suit different songs and playing styles.

The onboard bass boost circuit adds low-frequency emphasis when active mode is engaged. The volume control incorporates a push/pull selector, allowing the active circuit to be bypassed for passive operation. This gives players a direct option to continue using the bass when battery power for the active circuit is unavailable.

The bolt-on maple neck uses a scarf-joint design for dependable construction, paired with a satin finish and speed neck contour for a smooth playing feel. Its 12-inch-radius laurel fingerboard carries 24 jumbo frets, extending the available register while supporting articulate fretting. A Jackson hardtail bridge and sealed die-cast tuners complete a practical platform for connection to a bass amplifier, DI, pedalboard, or recording interface.

Design & Installation

The JS2P has a gloss-finished poplar body with a poplar burl top, a bolt-on maple neck, and a laurel fingerboard. Its offset Spectra Bass body, unique Jackson 2x2 headstock, black pickup covers, black hardware, and dome-style control knobs create a coordinated visual design. The hardtail bridge and sealed die-cast tuning machines support stable setup and everyday use.

Use a standard instrument cable to connect the bass to a bass amplifier, DI box, audio interface, or compatible effects chain. Set the volume, pickup blend, and bass boost to match the amplifier and musical context; pull the volume knob to bypass the active circuit when passive operation is preferred. Saddle-height and truss-rod wrenches are included for setup adjustments, while a case, amplifier, and cable are not listed among the manufacturer accessories.
