The ACC-PBR-9PJ 9-pin switching jack is an exact replacement for the item provided with the Fishman Powerchip product.
The 9-pin jack allows for stereo output, plus battery switching, for electric and acoustic guitar panel mount jack applications. It is useful as a replacement for the jack provided with our Powerchip product, or as an additional part, for users hoping to add a passive Powerbridge to a guitar with active magnetic electronics.
