The "JB" (a.k.a. "JazzBar") series of SoapBar pickups was released to cover the needs of new basses, or existing basses which happen to fit the dimensions of the various SoapBar pickups.

JB-series pickups can be used alone, or with other Lane Poor pickups in the SoapBar family or other families.

JB-series pickups share the same housing sizes as the other members of the SoapBar family (namely, the SB and HB pickups) and can be used interchangeably in basses which are routed for the same pickup size.

The JB-series pickups have a single coil with a narrow aperture. Like all other Lane Poor pickups, they can be used with any string spacings, since the pickup coil is continuous across the length of the pickup.
