For decades, vibrant microphones have been sent with the voice coil attached to the principal of the microphone's transformer, and maybe not introduced to soil (‘floating'). The microphone's event is typically connected to the wire shield, which is connected to the microphone amplifier's floor (see Rane's site for more discussion).
By and large, active microphones are extremely quiet devices as a result of the mixture of transformer isolation and balanced, flying sign lines throughout, as well as shielded, humbucking coils.

Well-known alternative is always to move the guitar pickup to a balanced result, just like a microphone. A similar strategy was printed that 2001 patent request like this Drum Machine Metal Online?
