Gibson 335 S A guitar collection is basically just like a powerful microphone coil. For many years, dynamic microphones have now been wired with the voice coil attached with the principal of the microphone's transformer, and perhaps not referenced to floor (‘floating'). The microphone's situation is typically attached to the cable shield, that will be linked to the mike amplifier's surface (see Rane's site for more discussion).
By and big, energetic microphones are very quiet units consequently of the combination of transformer isolation and healthy, flying indication lines throughout, as well as shielded, humbucking coils.
Therefore you will want to guitars? Guitars are notoriously affected by noise. Humbucking pickups are just an incomplete (though important!) solution. Well-known option is to float the guitar collection to a balanced result, just like a microphone. A similar idea was published this 2001 patent application like this Gibson 335 S?
