The brand-new offset body style was designed with the artist in
mind. The poplar body with large upper horn evenly distributes
weight throughout the instrument, providing perfect balance by
reducing neck dive for hours of comfortable playing. A bolt-on
maple neck with scarf joint design provides rock-solid reliability,
while the speed neck contour, 12”-16” compound radius
laurel fingerboard and 24 jumbo frets make for lightning-fast
playability.
The Spectra Bass JS3 provides a sound that is as unique as the
bassist playing it. Whether it be funk, hard rock or gospel, dual
passive Jackson medium-output humbucking pickups create
a monstrous low-end growl, while a HiMass™ bridge provides
enhanced stability, improved sustain and bolder tone. Tone can
be further refined and tweaked with a two-way toggle switch for
pickup coil splitting, 3-band EQ (active only), blend control and
volume control (with push/pull selector to bypass or engage the
active circuit for the 3-band EQ). With the push/pull selector,
you’ll never have to fear a battery running out and losing sound.
A quick pull on the volume knob will bypass the active circuit,
making it easy to regain sound from the bass without the use of
battery power.
Offering more boom for your buck, the 4-string, 34”-scale
Spectra Bass JS3 comes dressed in a new vivid Indigo Blue
finish with a unique Jackson 2x2 black headstock with an
understated J logo and black nickel hardware.
