I have just uncovered the pickups in my recently purchased 1996 Heritage 150 (Les Paul). The neck pickup has a chrome cover and when I lifted it from the body it said "Gibson USA". BUT... ...When I lifted the bridge pickup - which is a zebra-type pickup (cream/black; no chrome/nickel cover at all) the bottom of the pickup simply has a small, black, square sticker with a gold border and in tiny gold letters it says "Patent Applied For". Any idea on the potential origin/maker of this pickup??? Thanks in advance for your help!
