Good quality components (although the type of CTS pot appears unidentified and I find the standard 500K pots to be no better than Aplha), Decent Caps (if orange drops are your thing) and presumeably good soldering. It will be significant improvement over stock and the prices are great.
Personally I'd use one of MLP's vendors here (Jonesy or Martin six string) if I didnt build my own. I build for other people too but I'm expensive...
I understand what he is saying, I just don´t understand WHY he is saying that. I never said a word about replacing anything - and he seems to know even what will (NOT) be replaced!
I just came across this harness this on stewmac website and wondered how good they actually are, mainly because the CTS pots are not well identified. That´s why I want to know if someone actually have them installed.
BTW, my guitars were upgraded to RS Guitarworks, which I love.
