Mission Engineering Gemini 2 A best guitar collection is actually much like a vibrant mike coil. For decades, active microphones have already been sent with the voice coil attached to the primary of the microphone's transformer, and not recommended to ground (‘floating'). The microphone's event is typically linked to the wire guard, which can be attached to the mike amplifier's ground (see Rane's web site for more discussion).
By and large, active microphones are very calm units consequently of the combination of transformer isolation and healthy, suspended sign lines through the duration of, along with shielded, humbucking coils.
Therefore why not guitars? Guitars are notoriously overwhelmed by noise. Humbucking pickups are merely an incomplete (though important!) solution. The obvious answer is always to float your guitar pickup to a balanced result, being a microphone. An identical thought was printed this 2001 patent request such as Mission Engineering Gemini 2?
