Rock Band 2 Song List A electric guitar pickup is essentially much like a vibrant mike coil. For many years, vibrant microphones have been sent with the voice coil attached to the primary of the microphone's transformer, and perhaps not introduced to surface (‘floating'). The microphone's case is typically attached to the wire guard, which can be connected to the mike amplifier's ground (see Rane's web site for more discussion).
By and big, active microphones are extremely calm products as a result of the combination of transformer solitude and healthy, hanging indication lines throughout, as well as guarded, humbucking coils.
So why don't you guitars? Instruments are once affected by noise. Humbucking pickups are merely an incomplete (though crucial!) solution. The obvious answer would be to move practicing the guitar pickup to a healthy output, just like a microphone. A similar idea was printed that 2001 patent request like this Rock Band 2 Song List?
