Buck, I just had an idea. I took playing cards and found the number of cards closest to the thickness of the pickguard on the Hummingbird. 5 cards was close. I then measured the thickness of 50 cards with a ruler, and that was ~9/16" or ~0.56". So, the 5 cards are 1/10 of that, or ~0.056. Some errors in my technique, but this leads me to believe that the Hummingbird pickguard is probably 0.060.
houvin, if you look at the thick pickguards Gibson is using now, that'll give you a idea of what 0.060 is like.
