Neck position replacement humbucking pickup for Rickenbacker 4000 series basses that adds output and hum-cancelling, which makes it great for all styles of music. It also adds warmth, clarity, and increases the tonal range as it uses two ceramic magnets and special windings. Hand built in Santa Barbara, it also uses a chrome-plated nickel silver cover, 4-conductor lead wire, and is vacuum wax potted for squeal free operation.
