Ambient Guitar Pedals A electric guitar collection is essentially just like an energetic mike coil. For many years, powerful microphones have been sent with the voice coil attached with the principal of the microphone's transformer, and maybe not recommended to ground (‘floating'). The microphone's case is usually attached to the wire guard, which can be connected to the mike amplifier's soil (see Rane's site for more discussion).
By and large, active microphones are very quiet devices as a result of the mix of transformer solitude and healthy, suspended sign lines during, in addition to guarded, humbucking coils.
So why don't you guitars? Guitars are notoriously affected by noise. Humbucking pickups are merely a partial (though essential!) solution. The obvious alternative is to move the guitar pickup to a healthy output, being a microphone. A similar thought was printed that 2001 patent software like this Ambient Guitar Pedals?
