Description
The Bartolini M34CX brings the M3 soapbar formula to the neck position of a 4-string bass, pairing dual-coil humbucking construction with a tone profile that leans into low-end weight without losing definition up top.
Bartolini’s coil design here is voiced for depth: expect robust lows and low-mids that give your bass a solid foundation, while the treble response stays vibrant and clear rather than dull or muted. It’s the kind of pickup that fills out a mix without turning to mud, making it a solid choice for players who want a fuller, more three-dimensional low end from their neck pickup.
As a humbucker, it’s hum-canceling by design, so you get that added low-end punch and warmth without the 60-cycle noise that can plague single-coil setups.
- Position: Neck
- Coil configuration: Dual-coil humbucker (M3 soapbar)

If you’re rebuilding your bass’s electronics around a warmer, deeper voice while keeping quiet, noise-free operation, the M34CX is worth a close look — especially if you’re already running or planning EMG 35-size routing.
