Ibanez Acoustic Guitar Accessories A guitar pickup is actually similar to a powerful mike coil. For many years, dynamic microphones have been sent with the voice coil attached with the primary of the microphone's transformer, and maybe not referenced to soil (‘floating'). The microphone's case is typically connected to the cable guard, which can be linked to the mike amplifier's floor (see Rane's web site for more discussion).
By and big, dynamic microphones are extremely calm products as a result of the mixture of transformer isolation and healthy, suspended sign lines during, along with protected, humbucking coils.
So why don't you guitars? Guitars are notoriously plagued by noise. Humbucking pickups are just a partial (though important!) solution. The most obvious solution is to move the guitar collection to a healthy result, being a microphone. The same strategy was published this 2001 patent request like this Ibanez Acoustic Guitar Accessories?
