I'm writing this topic to thank all the users here, especially blueman335, that suggested me the 59n/C5 combo for my Epiphone SG. After a while using the C5, I've finally got the 59n and it's like I've bought a new guitar.
Thank you, everyone. As an advice, I'd recommend to every Epiphone owner here: REPLACE YOUR STOCK PICKUPS NOW!
As usual, sorry about my bad english.
