Greetings from the Tweed Hut Music Store, Vacaville, CA. USA! Established 2002, We do a great job and will not let you down!

The Jackson JS Series Spectra Bass JS3 was designed with the artist in mind. A poplar body with a large upper horn evenly distributes weight throughout the instrument, providing players with perfect balance for hours of comfortable playing. A bolt-on maple neck provides rock-solid reliability, while the speed neck contour and laurel fingerboard make for lightning-fast playability. 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 2-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.
