Martin Guitar Hard Cases A electric guitar collection is actually similar to a dynamic microphone coil. For many years, powerful microphones have been wired with the style coil attached with the primary of the microphone's transformer, and maybe not called to ground (‘floating'). The microphone's situation is normally attached to the wire shield, that is linked to the mike amplifier's ground (see Rane's web site for more discussion).
By and big, dynamic microphones are very quiet devices consequently of the mix of transformer isolation and healthy, suspended transmission lines through the duration of, in addition to guarded, humbucking coils.
So why don't you guitars? Guitars are notoriously overwhelmed by noise. Humbucking pickups are merely an incomplete (though important!) solution. The most obvious answer is always to float the guitar pickup to a healthy output, just like a microphone. An identical thought was printed that 2001 patent application such as Martin Guitar Hard Cases?
