Mine didn't. I have played in the worst of places with all sorts of loads and noise sources over the last 40+ years from the smallest bars to the largest theatres, with all sorts of electrical issues, including some flat miswirings we had to work around to keep from being electrocuted.Even EMG's need a bridge ground under difficult conditions like stage lighting and funky old wiring in recording studios. Believe me, I have been addressing this issue for over 40 years with working pro musicians. Even with a well-shielded instrument, tape wounds and heavily coated strings fail to reduce extraneous hum as there is no human connection to ground.
