For those after the arena-filling power of an active instrument and the classic look and feel of a J Bass, the Fender Flea Signature Active Jazz Bass captures the madman's signature style in a model ready for the stage. The custom-shaped, smooth-edged body in the familiar J Bass silhouette is complemented by a beefy bass humbucker and matched Aguilar OBP-1 18-volt preamp to produce bone-rattling output that will have everyone's eyes (and ears) on the low-end.
