By deduction I'd say yes, because those pups in the Ltd Ed Silverburst Epi TBs of yore are (six magnet) Epi guitar pups! Which is why they sound so awful - all middish without any treble or balls - and your friend, with all due respect, would be better advised to replace them with Gibson TB Plus guitar size pups (which fit in size as well) rather than waste time with irrelevant, even harmful cosmetics!!!
These young people ...
I sent my original pups to someone here in the forum (to get rid of them!), may he step forth now!!!
