Jackson’s JS Series Concert™ Bass models rock seismic sound, style and affordability. The five-string Concert Bass JS3V is a 35"-scale model featuring a lightweight and resonant poplar body and fully bound bolt-on maple neck with graphite reinforcement and scarf joint, and a 12"-16" compound radius amaranth fingerboard with 24 jumbo frets, classic sharkfin inlays and our classic pointed 5-in-line Jackson headstock. Jackson dual high-output humbucking bass pickups power a monstrous low-end growl that can be tweaked and refined with two volume controls (neck and bridge pickups) along with an active three-band EQ, while a Jackson HiMass™ bridge provides rock-solid stability.
