I just finished up with replacing the pickups / electronics in my Epi G-400 SG with gen-u-ine Gibson '61 tribute zebra pickups and the "circuit board" style pots / jack / switch. Needless to say, I'm pretty happy with the results. I did have to rout out the body cavities somewhat to fit the Gibson bits in properly but it was well worth the effort. For less than $500 USD total for guitar and electronics this thing sounds/plays GREAT!
