The K&K Sound Double Big Twin is a four-sensor double bass transducer developed specifically for jazz bass players. It harmonizes very well with jazz bass, because its transmission band includes very high and very low frequencies. The high frequency translation ensures a clean amplification of the finger attack with the picked bass. The low frequency translation refers to a desired very bassy sound picture.
Each string of your upright bass is detected separately with the K&K Double Big Twin. This results in an extraordinary balance of sound to accommodate even the pizzicato playing mode. The K&K Double Big Twin is easily mounted with the supplied double-sided adhesive film and doesn't require modification of the instrument itself. This adhesive film has been selected carefully because it proved to have excellent qualities for sound transmission. The connection jack is held in a special attachment clamp to be mounted between the A and D strings below the bridge.
The K&K Double Big Twin has enough output to drive your bass amplifier directly without the need for a preamp. If you are plugging into a PA system or mixer board, you may need a preamp to increase the signal strength to match that system. We highly recommend one of the K&K preamps for impedance adaptation and pre-amplification, such as the K&K Pure Preamp or the K&K Pure XLR Preamp, available separately.
