Guitar Effects Controller A electric guitar pickup is actually similar to a powerful microphone coil. For decades, dynamic microphones have been wired with the style coil attached to the primary of the microphone's transformer, and perhaps not referenced to ground (‘floating'). The microphone's event is typically linked to the wire shield, which can be connected to the mike amplifier's floor (see Rane's web site for more discussion).
By and big, powerful microphones are very quiet devices consequently of the mix of transformer isolation and balanced, hanging sign lines during, in addition to protected, humbucking coils.
Therefore you will want to instruments? Guitars are once overwhelmed by noise. Humbucking pickups are only a partial (though essential!) solution. The most obvious answer is always to float the guitar collection to a balanced output, being a microphone. The same thought was printed this 2001 patent application like this Guitar Effects Controller?
