Guitar Strings Redcliffe A best guitar pickup is actually similar to a vibrant microphone coil. For decades, vibrant microphones have already been wired with the style coil mounted on the primary of the microphone's transformer, and not referenced to surface (‘floating'). The microphone's case is usually connected to the wire guard, that will be attached to the mike amplifier's ground (see Rane's website for more discussion).
By and big, powerful microphones are very quiet products consequently of the mixture of transformer isolation and healthy, hanging sign lines for the duration of, as well as protected, humbucking coils.
Therefore you will want to guitars? Instruments are notoriously plagued by noise. Humbucking pickups are only a partial (though essential!) solution. The obvious option would be to move your guitar pickup to a healthy output, being a microphone. A similar idea was published this 2001 patent request like this Guitar Strings Redcliffe?
