The Bass Max is an upright bass transducer which uses a "sandwich" design with two piezos layered together, one facing up and one down. This allows for a quick and simple wedge-mount into a bridge wing and ensures even transmission from the strings and from the body of the instrument. It is very sturdy and has a high output signal that is balanced over the whole tone range. It is suitable for both arco and pizzacato playing styles because it transmits a broader mid frequency range. The 1/4" connection jack is held in place by a special attachment clamp mounted at the A & D strings between string holder and bridge. The 6" wrapped cable eliminates disturbance.
