The Jack Casady Signature Bass from Epiphone was designed by Rock and Roll Hall of Fame legend Jack Casady and is the culmination of years of experimentation by the Jefferson Airplane and Hot Tuna bassist to find an instrument with superior electric tone and the response of an acoustic bass. Featuring the Casady-designed JCB low-impedance pickup and a three-position rotary impedance control, this left-handed Jack Casady bass offers a wide range of tonal versatility.
