Passive humbucker for Rickenbacker basses. The benefit of this pickup is more power and sustain for those wanting a bigger push without tonal coloration. Alnico 5 magnets are the force behind this bridge replacement. It is suggested to replace your pickups as a set, however, it is not necessary. It is slightly larger than the stock bridge pickup, and so the original chrome mounting ring cannot be used with it. We supply a special phenolic mounting ring that goes well with our pickup, and will look great on your bass. - Number of Conductors: 1 - DC resistance: 8,6 kOhm - Colour: Black.
