i rececently bought a new output jack for my ovation. The old one was crackling and popping whenever the cable moved. the one i bought is a stereo jack with the three prongs sticking out. Also, it is the type that when you insert the cable, a piece of metal bends downward and touches the shaft. i was wondering if anyone had any wiring schematics that would help me out, i just cant get it to work. (The wires coming from the preamp are red, black, and white if that helps.)
