The RB-2A provides our RB bridge sensor and adds a very small preamp, a pair of integrated thumbwheel volume controls and a second sensor that fits to the fingerboard for that Rock-A-Billy string slap.

The RB sensor element is designed to fit in the wing slot of a bass bridge. Normal placement of the sensor is in the bass side slot.

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).
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.

Preamp: The unit utilizes one of our MicroPre 4 db buffer preamps. The preamp installs quickly and easily to the back side of the tailpiece and is held in place with some strong industrial strength velcro.

This pickup's capability is enhanced by the endpin jack preamp which gives the pickup the ability to be plugged directly into a P.A. or mixer.
