The BJ-02 PRO pickup is installed on the underside of the banjo head and is usually placed directly under and inline with the center foot of the bridge. The pickup is totally non-damping. It does not interfere in any way whatsoever with natural acoustic tone or output of the banjo. This particular placement of the sensor allows the pickup to "hear" just what the banjo is doing. The center foot of the bridge is driving the element directly for maximum output and clarity. This same placement of the element also gives the BJ-02 PRO its superior anti-feedback characteristics. It is very difficult for feedback to drive the pickup in reverse due to the overall stiffness of the bridge area.
