The Jack Casady Bass was designed by Rock and Roll Hall of Fame legend Jack Casady and is the culmination of years of experimentation by the Hot Tuna bassist to find an instrument with superior electric tone and the response of an acoustic bass. It features the Casady-designed JCB low-impedance pickup and a three-position rotary impedance control for a wide range of tonal versatility. Now, for the first time in a Fretless version!
