WOAH i disagree there. Cable capacitance does play a role in guitar tone; you lose high end, especially with the volume pot turned down.
It's never been a concern for me, I HATE that icepick in your forehead treble sound. I like a thicker, meatier sound.
I also think that most people probably couldn't tell the difference between a $100 3-foot long Monster cable and a 25-foot long $25 cable in a blindfolded test. This kind of stuff is psychoacoustics at work again. The same kind of snake oil hogwash as "oxygen-free copper".
I know, now you're going to tell me that you can hear the difference, blah, blah, blah. But can you really? Or are actually thinking that you can because you believe it is true? That's why people need to do a blindfolded test to really truly let their ears decide. I submit to you that it's in people's minds that a cable that costs four times as much and has a few pF/per foot less capacitance is so immensely better.
i certainly think (some will say its psychoacoustics i suppose, i guess i have to trust my ears) i can hear the difference between a curly and straight guitar lead... the treble roll off you get seems very noticeable but different to the treble roll-off you get with a long vs short lead (which is also obvious and undeniable). And i can tell the difference between my 10' cheapo cable and the 10' dimarzio one, why i havnt thrown the cheapo one out i will never know!!
You dont have to spend stupid money on cables but i wouldnt just accept cheap ones either. The dimarzio's are a fair price for a good sounding (and non tangling) cable, the award session cleartones seem good as well
I personally am not really concerned about cable capacitance. But I am concerned with how long it's going to last and how reliable it is likely to be. Of course, I don't want something with terrible capacitance, either.
I will agree with the coiled cable having more capacitance vs. a straight cable. The coiled cable has a lot more capacitance by design. I still think people that fork out ridiculous money for Monster cables and "oxygen free" copper are being, well, ripped off.
