I just removed one and swapped in a SD Classic Stack Jazz pup. The stock pup tone isn't bad, I just wanted to mess around with my beater. Has anyone here taken a good look at the stock Essex pup from China? I'm just curious about how they're designed and what their specs might be. I did see they're built with seperate pieces for the E/A and D/G strings. Anyone know anything about them or has anyone tested them for D.C. resistance/resonant peak? Just curious. Oh, one other thing: they're set in the covers with parafin wax.
