For many years, energetic microphones have been sent with the style coil attached with the primary of the microphone's transformer, and maybe not recommended to soil (‘floating'). The microphone's case is normally attached to the cable shield, which is linked to the microphone amplifier's soil (see Rane's web site for more discussion).
By and large, powerful microphones are very quiet products consequently of the mix of transformer isolation and healthy, floating transmission lines throughout, along with protected, humbucking coils.

The most obvious answer is always to move your guitar collection to a healthy result, just like a microphone.
