Custom Mic Stands A guitar collection is actually just like a powerful mike coil. For decades, dynamic microphones have now been wired with the style coil attached to the principal of the microphone's transformer, and maybe not recommended to ground (‘floating'). The microphone's case is normally connected to the cable shield, which will be connected to the microphone amplifier's ground (see Rane's site for more discussion).
By and large, powerful microphones are extremely quiet devices consequently of the combination of transformer isolation and balanced, hanging indication lines during, in addition to shielded, humbucking coils.
Therefore why not guitars? Instruments are notoriously affected by noise. Humbucking pickups are merely an incomplete (though crucial!) solution. The most obvious option is to float your guitar pickup to a healthy result, just like a microphone. The same idea was published this 2001 patent request such as Custom Mic Stands?
