X Series Spectra Bass SBXM IV With modern style, flexible tone and incomparable value, the Jackson X Series Spectra Bass SBXM IV takes the adventurous player on a bold bass odyssey, launching a commanding all-new entry in Jackson’s formidable neck-through-body bass lineup. The offset Spectra Bass body style was innovatively designed with the gigging musician in mind. Its poplar body has a larger upper horn that evenly distributes weight throughout the instrument for perfect balance and playing comfort. The graphite-reinforced through-body maple neck with scarf joint creates formidable sustain, with a speed neck contour, 12"-16" compound radius maple fingerboard and 24 frets for superior playability. The SBXM IV provides a full-sonic spectrum for even the most versatile and progressive bassists. Dual passive medium-output humbucking pickups create a dynamic foundation with punch, power and note articulation. Wide-ranging tonal command comes from a two-way toggle switch for pickup coil splitting, 3-band active EQ, blend control and volume control with push/pull selector to bypass or engage active circuit for the 3-band EQ. The push/pull selector eliminates the risk of losing sound due to a dead battery. A quick pull on the volume knob bypasses the active circuit, making it easy to regain sound from the bass without the use of battery power. This four-string bass also features a HiMass™ hardtail bridge that enhances sustain and improves note attack. Featuring a unique 2x2 black headstock with an understated “J” logo, the budget-friendly SBXM IV comes in a classic Snow White finish with gleaming gold hardware.
