JS Series Concert™ Bass JS3Q Jackson’s JS Series Concert™ Bass models rock seismic sound, style and affordability. The four-string Concert Bass JS3Q is a 34”-scale model featuring a lightweight and resonant poplar body with a beautiful quilt maple top, fully bound bolt-on maple neck with graphite reinforcement and scarf joint, and a 12”-16” compound radius amaranth fingerboard with 24 jumbo frets and classic pearloid sharkfin inlays. Dual Jackson high-output humbucking bass pickups provide a monstrous low-end growl, while HiMass™ bridge provides rock-solid stability. Tone can be shaped and refined with a pair of volume controls (neck and bridge pickups) and an active three-band EQ. Enjoy superior Jackson tone, value and vibe with the elegant JS3Q, available in either Cherry Burst or Transparent Black with black hardware and Jackson’s pointed 4-in-line headstock.
