Audio Technica Ath M70x A electric guitar collection is actually much like a dynamic microphone coil. For many years, dynamic microphones have been sent with the voice coil attached to the primary of the microphone's transformer, and perhaps not referenced to ground (‘floating'). The microphone's situation is usually attached to the wire shield, which is linked to the mike amplifier's ground (see Rane's website for more discussion).
By and large, powerful microphones are extremely quiet devices consequently of the mixture of transformer solitude and healthy, suspended indication lines throughout, along with guarded, humbucking coils.
So you will want to guitars? Instruments are notoriously affected by noise. Humbucking pickups are only a partial (though crucial!) solution. The most obvious solution is always to float practicing the guitar collection to a balanced result, being a microphone. A similar idea was printed this 2001 patent application like this Audio Technica Ath M70x?
