Pork Pie Throne A best guitar pickup is actually just like a vibrant microphone coil. For many years, powerful microphones have already been sent with the style coil attached to the primary of the microphone's transformer, and not referenced to ground (‘floating'). The microphone's case is normally attached to the cable guard, which is connected to the mike amplifier's surface (see Rane's site for more discussion).
By and big, active microphones are extremely quiet units consequently of the combination of transformer isolation and balanced, flying sign lines through the duration of, in addition to guarded, humbucking coils.
So you will want to instruments? Guitars are notoriously affected by noise. Humbucking pickups are just a partial (though essential!) solution. The most obvious alternative is to float your guitar pickup to a healthy output, being a microphone. The same idea was published this 2001 patent program like this Pork Pie Throne?
