If you click on my gear in my signature, you'll see one of the rarest, best shades of blue that Fender ever came out with...reverse metallic blueburst. I've never heard of blue pearl burst, but know of the regular blueburst and rev. metallic blueburst, plus about 4 or 5 other shades of opaque blue. Never heard of blue pearl burst.
Also, that H-S-S Fender Showmaster looks killer. I want one of those!
