John Mayer And The Dead A guitar pickup is basically just like a dynamic mike coil. For decades, vibrant microphones have been sent with the style coil mounted on the principal of the microphone's transformer, and not referenced to floor (‘floating'). The microphone's event is normally linked to the cable guard, that is connected to the mike amplifier's floor (see Rane's website for more discussion).
By and large, energetic microphones are extremely calm products as a result of the combination of transformer solitude and balanced, flying sign lines during, in addition to shielded, humbucking coils.
Therefore why not instruments? Instruments are notoriously overwhelmed by noise. Humbucking pickups are just a partial (though important!) solution. Well-known alternative would be to move your guitar collection to a healthy production, as being a microphone. An identical strategy was printed that 2001 patent software such as John Mayer And The Dead?
