Otaypanky, I don't mean to be argumentative, but did you learn that from personal experience or from second hand information?
I agree completely that when you use shielded cable, the lower the capacitance the better. An cable with too much capacitance will attenuate your high frequencies. What I'm not sold on is how much difference it makes in the 12" or so of guitar wiring loom.
The reason I ask though is I'm about to re-wire one of my guitars, for mechanical reasons, not electrical as it happens, but I need to grab some more cable to do so. If you've tried this out first hand I'd love to know what cable was used and where to get it so I can see/hear for myself
Also just to clear something up I've read today somewhere else.
Insulated wire, like the cloth covered "mojo" wire or state of the art Teflon wire, has no capacitance. You need two conductors to have capacitance. I have been looking everywhere to find some proof that there is any difference at all in the effect of insulation material on a waveform at audio frequencies, but not only can I not find proof apart from anecdotal, I can't even find an underlying theory as to why!
Premiere Guitar even published an article that states "The lack of plastic insulation resonances results in the good, natural sound....." when referring to cloth covered wire. I've spent the last hour trying to find any technical reference to the resonant properties of insulation and can't find a single one. I call major BS on that claim!!!!!!!!!!
If you want to get really, really technical, this is a good read on
Debunking Cable Resonance If you read it though you might note that at no point does anybody refer to the resonance of the insulating material. (because it's BS?)
