Truss Rod Cover A electric guitar pickup is basically much like a dynamic microphone coil. For decades, powerful microphones have been sent with the style coil attached with the primary of the microphone's transformer, and not referenced to surface (‘floating'). The microphone's event is usually attached to the wire guard, that is attached to the microphone amplifier's floor (see Rane's website for more discussion).
By and big, powerful microphones are very calm units as a result of the combination of transformer isolation and healthy, hanging transmission lines all through, as well as protected, humbucking coils.
Therefore why not instruments? Instruments are once affected by noise. Humbucking pickups are just a partial (though essential!) solution. The obvious option would be to move your guitar pickup to a healthy result, being a microphone. A similar idea was published that 2001 patent program such as Truss Rod Cover?
