Schertler STAT-B SET The Schertler STAT-B is Schertler's classic electrostatic bridge-mounted transducer. This SET includes Schertler's STAT-PRE preamplifer. Ideal in applications where high volume levels must not present a handicap, the STAT-B provides high feedback resistance while reflecting the natural sound of the Double Bass with a clear, well defined and "round" string tone. Schertler's patented STAT line of bridge pickups was designed by Stephan Schertler, a Bassist himself, for Bassists. Then too, just ask Charlie Haden, Rufus Reid and Larry Granadier who rely on Schertler pickups for their "live" sound. "THIS TRANSDUCER REPRODUCES THE SOUND OF MY BASS, STRINGS and FINGERS, NOTHING ELSE." - Charlie Haden The Schertler STAT-PRE preamplifier is the perfect choice for use with STAT series of pickups for classic stringed instruments. Compact, versatile and easy to use, the STAT-PRE provides power to the STAT-B pickup while allowing control of volume.
