Speaker Cables Audiophile A electric guitar collection is basically much like an energetic microphone coil. For decades, energetic microphones have been sent with the voice coil attached to the primary of the microphone's transformer, and maybe not recommended to floor (‘floating'). The microphone's case is usually attached to the wire guard, that will be attached to the microphone amplifier's ground (see Rane's website for more discussion).
By and big, powerful microphones are very calm devices as a result of the mix of transformer isolation and healthy, flying indication lines for the duration of, along with shielded, humbucking coils.
So why not instruments? Guitars are notoriously overwhelmed by noise. Humbucking pickups are just an incomplete (though essential!) solution. The most obvious answer is to move practicing the guitar pickup to a healthy production, as being a microphone. A similar idea was printed this 2001 patent application such as Speaker Cables Audiophile?
