Fishman Violin Output Socket

I use this for an M-100 piezo mandolin bridge. Using it effectively converts the M-100 to a Fishman M-200. Much superior to several other output jacks I have tried. Easy to solder up and fit. One problem on a mandolin is the thickness of the ribs being greater than for a violin. So anyone intending to use it on a mandolin may need to purchase a viola chinrest clamp (freely available) and take the screws off that to make a more stable fitting. This output jack socket is not the cheapest. But it has done what I needed very well.
