Behringer Line Mixer A best guitar collection is essentially just like a dynamic microphone coil. For decades, active microphones have now been sent with the style coil attached to the primary of the microphone's transformer, and maybe not introduced to floor (‘floating'). The microphone's event is normally attached to the cable shield, which is attached to the microphone amplifier's surface (see Rane's web site for more discussion).
By and big, energetic microphones are very calm devices as a result of the mixture of transformer solitude and healthy, suspended transmission lines all through, as well as shielded, humbucking coils.
Therefore why not guitars? Instruments are once affected by noise. Humbucking pickups are merely a partial (though crucial!) solution. Well-known solution is always to move your guitar pickup to a healthy output, just like a microphone. The same idea was printed this 2001 patent application like this Behringer Line Mixer?
