In 1983 Danish engineer Jørgen Wilson started the first attempts to develop a new pickup system for sound amplification of the double bass based on piezo transducers, which, placed on a string instrument, makes it possible to adjust volume on every single string manually. Wilson could with his trained ears as an amateur jazz bassist adjust the development proces of the Pickup system to its maximum capacities. The developed Wilson Pickup System turned out to be groundbreaking in the field of double bass amplification and has ever since resulted in a growing demand from bass players worldwide. Today the Wilson Pickup System is used by leading bassists all over the world.
