Metal Body Guitar A best guitar collection is actually just like a dynamic microphone coil. For many years, active microphones have already been wired with the style coil mounted on the primary of the microphone's transformer, and perhaps not recommended to floor (‘floating'). The microphone's case is normally connected to the cable guard, which can be connected to the mike amplifier's floor (see Rane's web site for more discussion).
By and large, active microphones are very calm units as a result of the mix of transformer isolation and healthy, floating sign lines during, in addition to shielded, humbucking coils.
Therefore why not guitars? Guitars are notoriously overwhelmed by noise. Humbucking pickups are just an incomplete (though important!) solution. The most obvious alternative would be to float your guitar pickup to a balanced result, as being a microphone. A similar idea was printed this 2001 patent application such as Metal Body Guitar?
