I am thinking about putting a couple of 59s in my LP, but I don't know if I should wire them in series or split besides the regular hook up. I called SD and the tech support told me that putting the 59s in series will make them sound fat like the P90s. However, my friend's Nighthawk and my American Deluxe Tele with the S-1 switch prove it otherwise. I wonder if any of you brothers and sisters has wired the 59 in series and tell me how it sounds.
