Fender Classic Player Triple Telecaster A best guitar pickup is basically much like a dynamic microphone coil. For many years, powerful microphones have already been wired with the voice coil attached with the primary of the microphone's transformer, and maybe not recommended to surface (‘floating'). The microphone's event is normally attached to the wire shield, which will be attached to the mike amplifier's ground (see Rane's web site for more discussion).
By and big, energetic microphones are extremely calm devices as a result of the mixture of transformer isolation and balanced, suspended transmission lines throughout, along with protected, humbucking coils.
Therefore why not guitars? Instruments are notoriously affected by noise. Humbucking pickups are only a partial (though important!) solution. Well-known alternative is to float the guitar pickup to a healthy output, just like a microphone. A similar thought was printed that 2001 patent program such as Fender Classic Player Triple Telecaster?
