Bass Master RB PLUS

The Bass Master RB Plus for Rockabilly Bass is the first double bass transducer system designed specifically for Rockabilly and Slap Bass!

We are proud to introduce this newly developed pickup system. At K&K Sound Systems, we have combined two transducers to create an integrated double bass pickup system designed to bring out the percussive and subtle fingerboard sounds, as well as strong and warm bass tones.

Each Bass Master RB Plus can be fine-tuned via the separate bass and treble controls within the dual channel preamp, providing an infinite range of combinations for every player and any style of play.

The first component, the popular Bass Max, is mounted in the bridge wing. Two transducers are combined using a sandwich technique, in order to maximize and enhance vibrations captured from the entire bridge. Due to its specialized construction, only one unit is necessary to provide an even signal from all four (or five) of the double bass' strings. Its strong midrange power is ideal for cutting through the mix in loud rockabilly situations, or providing a warm and supportive line for country bluegrass.

Our specially modified single transducer is ideal for capturing fingerboard sounds. Its unique size and shape allows precision placement and the equalization from the preamplifier lets the player blend in just the right amount of slap, growl, and other fingerboard sounds to reach their audience. This allows the player to achieve the exact sound coloration and effect they desire.

The Dual Channel Mixer has internal gain, bass, treble trim pots for each pickup, allowing impressive +/- 20dB tonal adjustments. External volume controls let you balance the volumes of the bridge and fingerboard transducers on the fly. A convenient belt clip is included with this compact preamplifier, which weighs a mere ten ounces with the battery installed. A six foot, high quality three conductor (1/4 inch stereo) cable is included to complete the package. The Bass Master RB Plus includes an extra output in the preamp. The Bass Master RB with only one output has been discontinued.
