Green Epiphone Les Paul A best guitar pickup is essentially just like a vibrant mike coil. For many years, active microphones have now been sent with the voice coil attached to the primary of the microphone's transformer, and maybe not referenced to soil (‘floating'). The microphone's situation is normally connected to the cable guard, that is connected to the mike amplifier's surface (see Rane's site for more discussion).
By and big, powerful microphones are very calm units as a result of the combination of transformer isolation and balanced, floating indication lines all through, as well as shielded, humbucking coils.
Therefore you will want to instruments? Instruments are notoriously overwhelmed by noise. Humbucking pickups are just an incomplete (though crucial!) solution. Well-known answer is to float your guitar collection to a balanced output, as being a microphone. The same idea was published this 2001 patent software like this Green Epiphone Les Paul?
