The Powerjack from Fishman is a miniature preamp in an elongated 1/4” endpin jack designed to provide active performance to a passive piezo pickup in an acoustic instrument. It replaces the existing endpin jack.
The Powerjack features a low-noise FET Class A input stage, and a bipolar Class AB output stage, yielding a signal-to-noise ratio of 94 dB.
It is powered by a 9V battery (available separately). Battery life is up to 12,000 hours.
