Seismic Audio Speakers A guitar pickup is essentially similar to an energetic mike coil. For many years, active microphones have been sent with the style coil attached to the primary of the microphone's transformer, and not referenced to surface (‘floating'). The microphone's event is normally connected to the cable guard, which is attached to the microphone amplifier's floor (see Rane's site for more discussion).
By and big, dynamic microphones are very calm devices as a result of the combination of transformer isolation and balanced, flying sign lines for the duration of, as well as protected, humbucking coils.
So why not guitars? Guitars are notoriously affected by noise. Humbucking pickups are merely a partial (though crucial!) solution. The most obvious alternative is always to move your guitar collection to a balanced output, as being a microphone. An identical thought was published this 2001 patent program like this Seismic Audio Speakers?
