Developed by Fishman Transducers, this is a pre-amp system for acoustic guitars that have Martin® Thinline 332® or other ceramic pickups. This system upgrades an existing Thinline 332® to a 332 Plus. The Active Jack is a state-of-the-art miniature circuit that is housed in a slightly elongated shielding cap on the back end of the jack.
