Double Bass Bridge A electric guitar pickup is essentially just like a vibrant mike coil. For many years, powerful microphones have now been sent with the voice coil attached with the primary of the microphone's transformer, and maybe not referenced to floor (‘floating'). The microphone's case is typically attached to the wire shield, that will be attached to the microphone amplifier's surface (see Rane's site for more discussion).
By and big, powerful microphones are very calm units consequently of the mix of transformer isolation and healthy, hanging transmission lines through the duration of, as well as protected, humbucking coils.
Therefore why not guitars? Guitars are once plagued by noise. Humbucking pickups are just an incomplete (though important!) solution. The most obvious solution is always to float the guitar pickup to a healthy production, being a microphone. A similar idea was printed this 2001 patent software such as Double Bass Bridge?
