Presonus Monitor Station A guitar pickup is basically just like a vibrant mike coil. For decades, vibrant microphones have already been wired with the style coil mounted on the principal of the microphone's transformer, and maybe not recommended to surface (‘floating'). The microphone's situation is normally linked to the cable shield, that is linked to the microphone amplifier's soil (see Rane's site for more discussion).
By and big, active microphones are extremely quiet products as a result of the combination of transformer solitude and healthy, suspended indication lines through the duration of, in addition to protected, humbucking coils.
So why not guitars? Guitars are once overwhelmed by noise. Humbucking pickups are just a partial (though crucial!) solution. The obvious alternative would be to float your guitar pickup to a healthy output, just like a microphone. The same thought was printed this 2001 patent application such as Presonus Monitor Station?
