Voodoo Labs Ground Control Pro A electric guitar collection is actually much like a dynamic mike coil. For many years, energetic microphones have been sent with the voice coil attached with the primary of the microphone's transformer, and maybe not introduced to ground (‘floating'). The microphone's situation is usually attached to the cable shield, which can be connected to the microphone amplifier's ground (see Rane's website for more discussion).
By and big, dynamic microphones are very quiet units as a result of the mix of transformer isolation and balanced, hanging transmission lines all through, along with guarded, humbucking coils.
So why not guitars? Instruments are once overwhelmed by noise. Humbucking pickups are just an incomplete (though important!) solution. The obvious solution is to move your guitar pickup to a healthy production, being a microphone. The same strategy was published this 2001 patent software such as Voodoo Labs Ground Control Pro?
