KK Sound Pure Resonator BB Resonator Guitar Pickup.
The Pure Resonator BB is designed especially for biscuit bridge resonator guitars. It features a screw-mounted pickup for best possible sound transmission with maximum feedback resistance.
The jack can be mounted externally or internally. The pickup comes pre-wired with an endpin jack, including an external mount "dual lock" fastening system. The jack can also be mounted internally if the dual lock is removed. An optional internal flush mount nylon jack is supplied as well.
