Studer Digital Audio Mixer A best guitar pickup is essentially just like a powerful microphone coil. For decades, energetic microphones have now been sent with the voice coil attached with the principal of the microphone's transformer, and not recommended to floor (‘floating'). The microphone's situation is typically connected to the wire guard, that will be attached to the mike amplifier's soil (see Rane's website for more discussion).
By and large, energetic microphones are extremely quiet devices consequently of the mixture of transformer isolation and healthy, floating sign lines all through, as well as guarded, humbucking coils.
Therefore why don't you guitars? Guitars are once affected by noise. Humbucking pickups are merely a partial (though essential!) solution. The most obvious alternative would be to move your guitar pickup to a healthy production, as being a microphone. An identical idea was printed this 2001 patent application such as Studer Digital Audio Mixer?
