Independent shopping perspective
The Korena take
Jackson's SBX IV is a right-handed, four-string bass with a 34-inch scale, satin-finished offset poplar body, and graphite-reinforced maple neck-through construction. The larger upper horn distributes weight for balance during extended playing. Its two passive medium-output humbuckers work with coil splitting, blend, volume, and active three-band EQ controls for broad sound shaping. A push/pull volume control bypasses the active circuit if the 9V battery dies, while the HiMass bridge has adjustable saddles for intonation adjustment.
Strong match
Who this is for
- Extended playing sessions where the larger upper horn's weight distribution supports balance and comfort.
- Performance situations where active EQ is wanted but a bypass is available if the 9V battery dies.
- Four-string bass parts needing coil splitting, blend control, and active three-band EQ adjustment.
Consider the trade-offs
When to look elsewhere
- Buyers who need a case or gig bag included with the bass.
- Players looking specifically for a five-string instrument.
