Universal Audio Apollo Firewire A electric guitar pickup is actually much like an energetic microphone coil. For many years, dynamic microphones have now been sent with the style coil mounted on the primary of the microphone's transformer, and not introduced to soil (‘floating'). The microphone's situation is typically connected to the cable guard, that is linked to the microphone amplifier's floor (see Rane's internet site for more discussion).
By and large, energetic microphones are very quiet units consequently of the combination of transformer isolation and healthy, suspended sign lines throughout, in addition to protected, humbucking coils.
Therefore you will want to guitars? Guitars are once plagued by noise. Humbucking pickups are just a partial (though crucial!) solution. Well-known solution is always to float your guitar pickup to a healthy productivity, being a microphone.
