I know that "J" on the sticker on the back of old SD humbuckers indicates that they were wounded by our pickup guru MJ. But I have an old Invader 7 (got it around 2003) which has a handwritten "J" on the red sticker on the BOX. Does anyone know what it means?
In fact, I don't even know whether this sticker is from the SD factory or the dealer. Also, the sticker on the back of the pickup got nothing but "B" (which means bridge model of course), see pics below.
