Ibanez 6 String Bass Guitar A electric guitar pickup is actually much like a powerful mike coil. For many years, energetic microphones have been wired with the voice coil attached with the principal of the microphone's transformer, and perhaps not called to soil (‘floating'). The microphone's case is usually attached to the cable guard, which is linked to the mike amplifier's soil (see Rane's site for more discussion).
By and big, vibrant microphones are extremely quiet products as a result of the mix of transformer isolation and healthy, hanging transmission lines during, in addition to protected, humbucking coils.
Therefore why not guitars? Guitars are once plagued by noise. Humbucking pickups are only a partial (though important!) solution. The most obvious option would be to move your guitar collection to a healthy output, as being a microphone. A similar strategy was published that 2001 patent application such as Ibanez 6 String Bass Guitar?
