Baby Blue Electric Guitars A electric guitar pickup is essentially much like an energetic mike coil. For decades, energetic microphones have now been sent with the voice coil attached with the principal of the microphone's transformer, and maybe not referenced to surface (‘floating'). The microphone's situation is normally attached to the cable guard, which will be connected to the microphone amplifier's floor (see Rane's site for more discussion).
By and large, vibrant microphones are extremely quiet devices as a result of the mix of transformer isolation and healthy, floating sign lines throughout, in addition to protected, humbucking coils.
So why don't you instruments? Instruments are once overwhelmed by noise. Humbucking pickups are just an incomplete (though important!) solution. The most obvious alternative is always to move your guitar pickup to a healthy production, being a microphone. A similar thought was printed that 2001 patent application like this Baby Blue Electric Guitars?
