I am having a bit of trouble wiring my guitars with 2 wire and 4 wire pickups. My arrangement is 2 hum, 1 vol, 1 tone, 3 way, 500k cts pots and .047 cap. I have 2 wire duncan pickups in the neck and 4 wire BL 500 XL in the bridge. Of the two I have wired, I can get sound out of them when plugged in and playing open but as soon as I rest my hand on the bridge or fret a note I get tons of buzz. Any ideas, help, input, etc would be appreciated.
