I'm about to cut into my favorite Shure 520D and want to do so with confidence. FJM gave me the following advice, which I believe, I just want to be reassured that others have had positive outcomes as well. FJM states "If the mic uses all three wires inside the shell it's wired dual. Those 2 little screws on the side of the mic hold the cartridge in. Remove the cartridge to see. To wire it single high impedance you cut the red wire and insulate the end then wire the blue wire to the shield and the black wire to the tip of the 1/4" plug. If you're not sure which cord wire is tip just take the sleeve off the plug end of the jack and look."
