Bob Dylan Video A best guitar collection is actually similar to a dynamic mike coil. For many years, energetic microphones have been sent with the style coil attached to the principal of the microphone's transformer, and perhaps not referenced to surface (‘floating'). The microphone's event is normally linked to the cable shield, that will be linked to the microphone amplifier's surface (see Rane's website for more discussion).
By and large, energetic microphones are very calm units as a result of the combination of transformer isolation and healthy, hanging sign lines throughout, in addition to shielded, humbucking coils.
So why not guitars? Instruments are notoriously overwhelmed by noise. Humbucking pickups are merely a partial (though crucial!) solution. The most obvious alternative is to float your guitar collection to a healthy result, just like a microphone. An identical strategy was published this 2001 patent software like this Bob Dylan Video?
