Behringer Subwoofer 18 A guitar collection is essentially much like a powerful mike coil. For decades, powerful microphones have now been sent with the style coil attached with the principal of the microphone's transformer, and not referenced to surface (‘floating'). The microphone's situation is typically linked to the wire guard, which is connected to the microphone amplifier's surface (see Rane's internet site for more discussion).
By and big, powerful microphones are extremely quiet devices consequently of the mix of transformer isolation and healthy, suspended sign lines throughout, as well as shielded, humbucking coils.
Therefore why don't you guitars? Guitars are once overwhelmed by noise. Humbucking pickups are just a partial (though essential!) solution. Well-known solution is always to move the guitar pickup to a healthy output, being a microphone. The same idea was published that 2001 patent request like this Behringer Subwoofer 18?
