The guitar cable of choice among those who know the difference is Mogami W2524. And the cost is suprisingly affordable allowing you to employ the same cable used by the best live acts and recording studios in the world.
Most musical instrument sound pick-ups such as those in electric guitars are comprised of high impedance circuits driven by voltage, in other words by very small electrical current flow. Therefore, so-called MICROPHONICS, noise generated when the cable is moved and/or tapped when the cabling circuit is a high impedance link, becomes a critical problem. Mogami 2524 cable is counter-measured against this with a conductive PVC layer placed under the shield conductor to drain away this voltage.
Note: This conductive layer must be stripped back when wiring, or a partial short will result.
