Telephone Vocal Effect Garageband A electric guitar collection is essentially similar to a powerful mike coil. For decades, energetic microphones have been sent with the voice coil attached to the principal of the microphone's transformer, and maybe not introduced to floor (‘floating'). The microphone's event is normally linked to the cable shield, that will be connected to the microphone amplifier's ground (see Rane's site for more discussion).
By and large, energetic microphones are extremely calm units consequently of the mix of transformer isolation and healthy, flying indication lines all through, as well as guarded, humbucking coils.
So why not guitars? Instruments are notoriously overwhelmed by noise. Humbucking pickups are only a partial (though crucial!) solution. The most obvious answer is always to move the guitar pickup to a balanced output, just like a microphone. An identical thought was printed this 2001 patent program like this Telephone Vocal Effect Garageband?
