Korn Bassist Fieldy A best guitar pickup is essentially much like an energetic microphone coil. For decades, powerful microphones have already been sent with the voice coil attached to the principal of the microphone's transformer, and perhaps not referenced to ground (‘floating'). The microphone's event is typically attached to the cable shield, which is attached to the mike amplifier's surface (see Rane's website for more discussion).
By and big, powerful microphones are very calm units as a result of the mixture of transformer isolation and healthy, hanging indication lines throughout, along with protected, humbucking coils.
Therefore why not instruments? Guitars are notoriously overwhelmed by noise. Humbucking pickups are just a partial (though important!) solution. Well-known option is to move your guitar pickup to a healthy result, as being a microphone. The same strategy was published that 2001 patent request such as Korn Bassist Fieldy?
