I just got myself a Gibson SG. It sounded very muddy, especially the neck p.u. so I changed the very old strings. Still have a dark, muddy tone in the neck position. I have heard better tone from a bridge pickup as well, but it is useable at this point. The pots are dimarzio 500k's and the wiring matches the Gibson schematic. The neck tone pot does roll off what treble is there but sounds very dark on 10. The caps are marked 223. Would .047's fix this or do I have a bad pot? OR is this a pickup replacement deal? BTW, my other humbucker guitar sounds great through my rig, as does my Tele and Strat. So, I don't think this is a amp issue. Thanks for your help.
