For many years, active microphones have now been sent with the style coil attached with the primary of the microphone's transformer, and maybe not introduced to ground (‘floating'). The microphone's situation is usually linked to the cable guard, that will be linked to the mike amplifier's ground (see Rane's web site for more discussion).
By and large, active microphones are very calm products consequently of the mix of transformer isolation and healthy, suspended transmission lines throughout, in addition to shielded, humbucking coils.
Therefore you will want to guitars? Guitars are once overwhelmed by noise. Humbucking pickups are merely a partial (though important!) solution. The obvious alternative is to move practicing the guitar collection to a balanced output, just like a microphone.
