Tak apropos grubości żyły, czym jest cieńsza i ma mniejszą "pojemność" jest mniejszy efekt naskórkowy - mniej strat góry etc. Stąd wspomniane przez Commelinę DieHardy brzmiały jaśniej.

"Lower cable capacitance allows more of the natural "brightness," "presence," or "bite" of an instrument to reach the amp, which in turn allows the treble controls to be run lower, reducing hiss and other unwanted noise. High-frequency loss from the cable gradually becomes audible and objectionable depending on the source, the amplification and other circumstances. There is no point at which high-frequency loss suddenly appears or disappears. Raising the source impedance or increasing the length of the cable increases the loss. Guitars typically have much higher source impedances at higher frequencies because of the inductive nature of their pickups, which aggravates the effect of cable capacitance. A guitar will often sound noticeably "muddier" when run through a 40-foot cable, while keyboard instruments, samplers, mixers and other line-level devices with low source impedances can usually drive cable runs of hundreds of feet without problems."

Co mówi o kablach inżynier? Dziadek Bill Lawrence:

"Why Low Capacitance?

1. The higher the capacitance of a cable, the less highs reach the amplifier.

2. High-capacitance cables shift the resonance towards the lower frequencies which dramatically alters tone. For example, Jimi Hendrix used a coiled cord with 3,000 picofarads (.003 microfarads), shifting the resonance below 2,000 Hertz on his Strats. This was the secret of Jimi's tone. Shifting the resonance frequency at 2,000 Hertz has a similar effect to a midrange boost. However, when he recorded and needed a typical Strat sound for some tracks, Jimi switched to a short, low-capacitance cable.

3. There are some very expensive high-capacitance cables on the market with a sound you might like for some tunes, but then you are stuck with that one sound. Using a low-capacitance cable, you can easily change the circuit capacitance by using a push-pull tone control to switch capacitors -- one capacitor for clean sounds and another for distortion. This allows you to choose the right capacitor values to match the pickups, aiming for a 600-700 Hertz resonance for clean sound and a 1500-2200 Hertz resonance for distortion."
