We use the term ‘Reissue’ to refer to Fusion body style instruments made with a double edge around the entire body. This style of body was a key feature of the original ZETA Jazz violins. In addition, as part of the ‘Reissue’ project . . . ZETA also reintroduced our original ‘Imbus’ neck, a ’92 JLP Jazz Reissue preamp, and the Signature ‘Jean-Luc Ponty’ model Jazz Violin. All ZETA Jazz bridge instruments, ie Jazz Fusion and Jazz Imbus models, come with the ’92 JLP Jazz Reissue preamp installed.
