Roc N Soc Backrest A best guitar collection is essentially just like a dynamic microphone coil. For many years, vibrant microphones have already been wired with the voice coil attached to the principal of the microphone's transformer, and perhaps not recommended to ground (‘floating'). The microphone's case is typically linked to the wire shield, that will be connected to the microphone amplifier's ground (see Rane's web site for more discussion).
By and big, powerful microphones are extremely quiet units consequently of the mix of transformer isolation and balanced, floating transmission lines during, as well as guarded, humbucking coils.
So why not guitars? Guitars are once overwhelmed by noise. Humbucking pickups are only an incomplete (though crucial!) solution. Well-known alternative is always to move the guitar pickup to a balanced result, as being a microphone. The same thought was published that 2001 patent request like this Roc N Soc Backrest?
