Here's what Seymour Duncan say about the Rickenbacker humbucker:
Humbucking upgrade for 4000 series basses adds output and hum-canceling. Great for all styles of music.
This Rickenbacker neck position replacement adds warmth, clarity, and increases the tonal range over stock a Ric neck pickup. We use two ceramic magnets and special windings to achieve this boost. This pickup is also slightly hotter and warmer than the originals, as well as hum-cancelling. Hand built in Santa Barbara, CA, the Rickenbacker neck position replacement pickup uses ceramic magnets, a nickel silver cover, 4-conductor leadwire, and is vacuum wax potted for squeal free operation.
