Gotoh 12 String Electric Guitar Bridge A electric guitar pickup is essentially much like a vibrant microphone coil. For decades, active microphones have now been wired with the style coil mounted on the primary of the microphone's transformer, and maybe not referenced to soil (‘floating'). The microphone's situation is normally connected to the wire shield, that will be linked to the mike amplifier's soil (see Rane's site for more discussion).
By and big, active microphones are extremely quiet units as a result of the combination of transformer solitude and balanced, suspended transmission lines during, as well as protected, humbucking coils.
So why not guitars? Instruments are once plagued by noise. Humbucking pickups are just a partial (though crucial!) solution. The obvious option would be to float practicing the guitar pickup to a healthy output, being a microphone. A similar idea was printed that 2001 patent request such as Gotoh 12 String Electric Guitar Bridge?
