Electric Guitar Slap Bass A guitar collection is essentially just like a dynamic microphone coil. For decades, active microphones have been wired with the style coil attached with the primary of the microphone's transformer, and not called to floor (‘floating'). The microphone's situation is normally connected to the cable guard, that is connected to the mike amplifier's floor (see Rane's internet site for more discussion).
By and big, active microphones are extremely calm devices consequently of the mix of transformer isolation and healthy, hanging sign lines during, along with protected, humbucking coils.
Therefore why not guitars? Instruments are notoriously overwhelmed by noise. Humbucking pickups are only an incomplete (though essential!) solution. The obvious alternative would be to float the guitar pickup to a healthy output, just like a microphone. A similar idea was published that 2001 patent request like this Electric Guitar Slap Bass?
