Best Small Digital Audio Mixer A guitar pickup is essentially similar to a dynamic mike coil. For decades, vibrant microphones have already been sent with the voice coil mounted on the primary of the microphone's transformer, and perhaps not referenced to floor (‘floating'). The microphone's event is normally attached to the cable guard, which can be attached to the mike amplifier's soil (see Rane's website for more discussion).
By and large, powerful microphones are extremely calm products as a result of the mixture of transformer isolation and balanced, floating transmission lines through the duration of, along with guarded, humbucking coils.
Therefore why not instruments? Guitars are once affected by noise. Humbucking pickups are only a partial (though crucial!) solution. The obvious solution would be to float the guitar pickup to a balanced output, being a microphone. The same idea was published this 2001 patent program like this Best Small Digital Audio Mixer?
