I was in Sam Ash today picking out a new capo and overheard some guy who was buying a guitar with active pickups talking to the luthier. I couldn't see the front of the guitar but from the back it looked like a Jackson. At least, the pointy headstock made it look like a Jackson.
Anyway, the buyer was telling the luthier that he wanted such and such brand strings, replace the tuners with 'this kind' and to order the EMG solderless kit to "replace the factory junk." He rambled on for a few minutes about the "garbage factory wiring, pots and jacks that are in most big brand guitars nowadays."
I've heard of people replacing the factory wiring and electronics on guitars like PRS SE's and other Korean-made guitars, but does it really make a difference?
I mean, unless I went from passive to active or vice versa, I've never just entirely replaced everything.
*Sorry if this has already been discussed on here, I couldn't find anything.
I'd be curious to hear what others' opinions are. I do know there's a whole thread on using different pots for different effects especially when doing stuff like making your tone knob a lowcut.
I imagine there probably is some benefit to be gained otherwise so many people wouldn't take out their tone knob completely in order to get more gain/bite/whatever. It obviously effects the sound.
edit - also a luthier is someone that makes guitars, so if he was buying a jackson it wouldn't be handmade by the guy at guitar center. Also he wouldn't be talking about redoing all the wiring in mass produced guitars.
