Guitar Amplifier Head Vs Combo A best guitar pickup is actually just like an energetic mike coil. For decades, vibrant microphones have been sent with the voice coil mounted on the primary of the microphone's transformer, and not referenced to surface (‘floating'). The microphone's case is typically linked to the wire shield, that is linked to the mike amplifier's surface (see Rane's site for more discussion).
By and big, vibrant microphones are extremely quiet devices consequently of the combination of transformer isolation and healthy, suspended sign lines all through, as well as shielded, humbucking coils.
So why not guitars? Instruments are once overwhelmed by noise. Humbucking pickups are just an incomplete (though essential!) solution. The most obvious answer is always to move your guitar collection to a healthy production, as being a microphone.
