billm90 Posted December 4, 2007 Report Share Posted December 4, 2007 I built a piezo classical style bridge, one piezo per each string. I wired it directly to a mono jack (no pre amp yet, runnign tests) I am currently getting a hum. this is on a nylon guitar, so only the 3 low strings are grounded. the hum stops when I touch the bottom 3 strings. Will running a ground shield around the lead wires remove the hum? Quote Link to comment Share on other sites More sharing options...
