Power Amplifier Lm3886 A best guitar pickup is essentially much like a vibrant mike coil. For decades, powerful microphones have been sent with the voice coil attached to the primary of the microphone's transformer, and not referenced to soil (‘floating'). The microphone's situation is normally attached to the cable shield, which can be linked to the mike amplifier's soil (see Rane's site for more discussion).
By and big, powerful microphones are very calm devices consequently of the mixture of transformer solitude and balanced, flying transmission lines all through, as well as protected, humbucking coils.
Therefore why don't you instruments? Instruments are notoriously affected by noise. Humbucking pickups are just an incomplete (though crucial!) solution. Well-known solution would be to move the guitar collection to a healthy productivity, being a microphone. The same strategy was printed that 2001 patent request like this Power Amplifier Lm3886?
