Gibson Les Paul Studio Faded T A best guitar pickup is essentially much like a vibrant mike coil. For many years, energetic microphones have been wired with the style coil mounted on the primary of the microphone's transformer, and maybe not referenced to floor (‘floating'). The microphone's situation is typically linked to the wire shield, which can be linked to the microphone amplifier's floor (see Rane's site for more discussion).
By and big, vibrant microphones are extremely calm products consequently of the mix of transformer isolation and balanced, hanging indication lines throughout, 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 answer is always to float the guitar collection to a balanced production, just like a microphone. A similar strategy was printed this 2001 patent application such as Gibson Les Paul Studio Faded T?
