Sir sigjoys, why'd you change your nut to a deerbone? And how much did it cost you to mod your sz520?
plastic kasi yung old nut. i have many experiences with plastic nuts, madali kasi masira so i opted to replace it with deer bone. sorry sir but di ko na ma-recall kung magkano. just ask jun, reasonable naman yung price nya in this work stuff.
i did the mods myself. i just bought the SD '59 and JB PUs and 3 push-pull pots at AP. i studied the wiring of the sz520 and got some inspiration from strat controls, coil split, page's out-of-phase, and guitars without tone controls. after i got the stuffs, studied the diagram over and over, and a liter of confidence, i did it. though i have made mistakes, it found a way to correct it. in the end, i appreciate the it. from the previous 3 combinations, i can have 9 possible combinations that i can do on the SZ520.
