National KNA DB-1 Double Bass Pickup

Portable piezo pickup for double bass.

DB-1 faithfully reporduces the breadth of tone and dynamic range of your instrument without modification. A wood-encased piezo sensor installs in eye slot of the bridge, held in place via friction. Neatly-finished shim discs ensure the perfect fit. The 1/4″ jack housing secures non-destructively to the tailpiece with a screw assembly at the string eye.  DB-1 is entirely passive, designed to work flawlessly with your favorite amplifier or colored via a preamp of choice.
