RB-2A - Rock-a-Billy Bass Pickup with Additional Fingerboard Sensor, Preamp, and Twin Volume Controls

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.

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). 
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.

Amplification
