The RB-2 (passive) provides our RB bridge sensor, black jack assembly and adds a second sensor that fits to the fingerboard for that Rock-A-Billy string slap. Included with the RB-2 is a pair of integrated thumbwheel volume controls for balancing the pickups. The controls mount to the underside of the fingerboard. Sound Clips: Clip 1 Technical Main Sensor: The RB sensor has a nominal thickness of 0.25" (6.35mm) and requires a wing slot opening of approximately 0.225" (5.7). Normal placement of the sensor is in the bass side wing slot.The fit of the sensor in the slot is meant to be snug and there is intended to be a slight interference fit. The sensor will compress slightly as it is pushed into the wing slot. Extra Slap Sensor: This extra pickup installs to the underside of the Bass fingerboard with 3M VHB mounting tape. Volume Controls: The RB-2 comes with thumbwheel volume controls that mount to the underside of the fingerboard with 3M VHB mounting tape. Black Jack Assembly: Provided with the RB-2, the black jack assembly simply clips between the D and A strings just above the tailpiece. The output jack itself is a standard 1/4". Installation Instructions: RB-2 (passive) pdf Amplification The passive RB pickup models work perfectly well and sound good when plugged straight into any decent quality bass amp. As with any pickup, the sound can be further enhanced with an outboard preamp. If you require the ability to plug directly into a P.A. or mixer then you may wish to add our Mini Pre belt clipable preamp.
