X Series Concert™ Bass CBXNT DX IV The all-new Jackson® X Series Concert™ Bass CBXNT DX IV is a highly versatile bass designed for one express purpose—bringing the thunder to your music. Upgraded electronics, classically brutal style and fast, efficient playability make this entry into the lineup a fundamental force to be reckoned with. Perfect for rock or metal—or other styles that demand low, punchy bass—this instrument is an unbelievable value. This 34”-scale bass pairs a poplar body with a graphite-reinforced neck-through-body design that generates formidable sustain, while the speed maple neck contour, 12"-16" compound radius bound maple fingerboard and 24 jumbo frets make for lightning-fast playability. The heart of this four-string beast is a Jackson J-style bridge pickup and Jackson P-style neck pickup, mated to an active 3-band EQ circuit for adding punch, cut, rumble or grunt to your sound. A brand-new stylish chrome Jackson Bass Bacher IV hardtail bridge enhances note attack and sustain without altering your carefully crafted tone while the sealed die-cast tuning machines keep the strings in tune, no matter how hard you dig into them.
