Description
If your 5-string needs low B authority without turning to mud, the M55CBC set is Bartolini’s answer. This is the M5 soapbar footprint (1.5″ x 4.5″) in dual-coil form, sold as a neck-and-bridge pair from the Classic Bass (CB) series — Bartolini’s passive line tuned for a wider, more open frequency window than their standard offerings.
The dual-coil design leans into weight down low, with strong lows and low-mids that keep a five-string’s B and E strings punchy and defined rather than woolly. Where these pickups distinguish themselves is up top: the Classic Bass voicing pulls out extra air and articulation in the treble, so pick attack, string noise, and note separation all stay audible even as the bottom end does its job. It’s a balance that suits players moving between slap, fingerstyle, and pick technique on the same instrument.
Each pickup measures 1.50″ (38.10mm) wide by 4.50″ (114.30mm) long, and both are cast in epoxy — a Bartolini staple that locks the windings down to kill microphonics and unwanted feedback, even at higher gain or stage volume.
