J-Style

Powerful drop-in preamps for J-Style basses. These have been designed to fit without any physical changes to the instrument itself* including enough space for a standard 9V battery to sit beneath the electronics. That said, all units are designed to operate up to 18V in which case a separate battery compartment will be necessary with most J-Style basses.
