Schatten Rock-a-Billy Bass Pickup with fingerboard sensor volume controls RB-2

Description

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.
The output jack itself is a standard 1/4".
