Guitar Wah Pedal On Bass A electric guitar collection is actually similar to a dynamic microphone coil. For decades, energetic microphones have already been sent with the voice coil mounted on the principal of the microphone's transformer, and not called to soil (‘floating'). The microphone's event is usually attached to the wire shield, which can be linked to the mike amplifier's soil (see Rane's site for more discussion).
By and large, active microphones are extremely quiet units as a result of the combination of transformer isolation and healthy, flying sign lines during, as well as protected, humbucking coils.
Therefore why don't you guitars? Guitars are notoriously affected by noise. Humbucking pickups are merely a partial (though important!) solution. Well-known option would be to float practicing the guitar collection to a healthy output, just like a microphone. A similar thought was printed this 2001 patent application like this Guitar Wah Pedal On Bass?
