Independent shopping perspective
The Korena take
David Ellefson’s 30th Anniversary Concert Bass CBX IV brings a poplar body, ergonomic contours, and a neck-through quartersawn maple neck to a four-string layout. Its 12- to 16-inch compound-radius laurel fingerboard becomes flatter farther up the neck for technical playing. EMG P and J pickups feed a three-way selector, volume control, and bass/treble EQ. The HiMass bridge is designed for stronger attack, extra clarity, and enhanced sustain. It is finished in Quicksilver with black hardware.
Strong match
Who this is for
- Technical four-string passages that use a fingerboard flattening toward the upper frets.

- Building P/J pickup sounds with selectable positions, volume, and bass/treble boosts.
Consider the trade-offs
When to look elsewhere
- Left-handed players; this model is right-handed.
