Dimebag Darrell Amp A electric guitar collection is basically similar to a vibrant microphone coil. For decades, active microphones have already been sent with the style coil attached with the primary of the microphone's transformer, and perhaps not introduced to soil (‘floating'). The microphone's case is typically attached to the cable shield, which is connected to the microphone amplifier's ground (see Rane's web site for more discussion).
By and big, powerful microphones are very quiet products consequently of the mixture of transformer isolation and balanced, suspended sign lines for the duration of, along with shielded, humbucking coils.
Therefore you will want to instruments? Instruments are notoriously affected by noise. Humbucking pickups are merely a partial (though important!) solution. The most obvious option is to move the guitar pickup to a balanced production, being a microphone. The same idea was printed this 2001 patent application such as Dimebag Darrell Amp?
