Jackson Guitars Introduces X Series Signature David Ellefson 30th Anniversary Concert Bass CBX IV

Earlier this year, Jackson Guitars and David Ellefson celebrated three decades since Megadeth’s Rust in Peace as well as the company’s first five-string bass by introducing the X Series Signature David Ellefson 30th Anniversary Concert Bass CBX V. Now they’re following it up with a four-string version, dubbed the CBX IV. The instrument has the bassist’s personal touches and pays homage to his first-ever Jackson bass.

“This bass truly represents the origin story of my relationship with Jackson, tracing back to the late-1980s when the company built my very first Quicksilver Concert Bass, just like this one,” said Ellefson. “Right down to the feel of the body and neck, the layout of the controls and its thundering rich tone, this bass is a modern representation of that exact same instrument of yesteryear. By revisiting our past, I’d say we created an even better instrument for today.”

Jackson builds the anniversary model with a poplar body, a through-body maple neck, and a laurel fingerboard. The neck is made from quartersawn lumber and features a scarf joint plus graphite-reinforcement rods. The fingerboard is also brought up to date with a 12”-16” compound radius that flattens out up the neck for comfort and speed.

The bass is fitted with a set of EMG P/J pickups with a three-way toggle switch and a two-band EQ with bass and treble boosts. Other features include a HiMass bridge, pearled shark fin neck inlays, a black “Radiation” headstock logo, and Ellefson’s signature on the back.
