Fender Telecaster Neck A electric guitar pickup is actually just like an energetic microphone coil. For decades, active microphones have already been wired with the voice coil mounted on the primary of the microphone's transformer, and perhaps not called to ground (‘floating'). The microphone's event is usually connected to the cable guard, that will be connected to the mike amplifier's floor (see Rane's website for more discussion).
By and big, powerful microphones are extremely quiet devices as a result of the combination of transformer isolation and balanced, floating transmission lines all through, along with protected, humbucking coils.
Therefore why don't you guitars? Instruments are once affected by noise. Humbucking pickups are only an incomplete (though important!) solution. The most obvious alternative would be to move your guitar pickup to a healthy production, just like a microphone. A similar idea was printed that 2001 patent program such as Fender Telecaster Neck?
