Les Paul Logo A guitar collection is actually similar to an energetic microphone coil. For many years, energetic microphones have been sent with the voice coil mounted on the principal of the microphone's transformer, and not called to surface (‘floating'). The microphone's event is usually attached to the cable shield, which will be connected to the microphone amplifier's soil (see Rane's site for more discussion).
By and big, energetic microphones are very calm products as a result of the mix of transformer isolation and balanced, floating sign lines throughout, along with protected, humbucking coils.
Therefore you will want to instruments? Instruments are notoriously overwhelmed by noise. Humbucking pickups are just a partial (though crucial!) solution. Well-known option is to float your guitar collection to a healthy result, just like a microphone. A similar idea was published that 2001 patent software like this Les Paul Logo?
