I bought an 89 Strat about 5 years ago and it had a SD Humbucker in the bridge that sounded great. Well I noticed it didn't look like any SD pickup I'd ever seen it has staggerd pole pieces. Well not to long ago I wanted to put one in another on of my Strats so I took my SD pickup out of my strat flipped it over and it says MGJ. Well I cant find out anything about this pickup please help a brotha out.
