Description
The W4CBC-B is Bartolini’s W4-shaped soapbar built specifically for the neck position, measuring 4.06″ / 103.25mm long by 1.74″ / 44.20mm wide — a straightforward retrofit for basses already routed to this footprint.
Inside, a dual-coil design delivers the kind of low-end weight and low-mid push that neck pickups are known for, but it doesn’t stop there. This is part of Bartolini’s “Classic Bass” line, a passive series voiced with an extended, more resonant frequency window than typical vintage-style units. Translation: you still get the fat, warm foundation from the low strings, but the top end opens up with genuine clarity and sparkle instead of getting buried under mud.
That extra reach into the treble doesn’t come at the expense of body — the low and low-mid content stays fully intact, so you’re gaining articulation and definition on top rather than trading away punch below.
Every W4CBC-B is epoxy-cast, a construction detail that locks the coil windings in place to kill microphonic noise and squash unwanted feedback before it starts. It’s the kind of build quality that matters most on stage, where an uncontrolled hum or a dying-note squeal can wreck a take.
