John Mayer Tone
It is my bias opinion that Victoria Reverberato is the most important part of John's rig. And many other player's rig, for that matter! To me, the sweetness it adds to the signal is reminiscent of the same mojo provided by the original Maestro Echoplex EP2. Plug the Reverberato into the front of any amplifier and that amplifier simply sounds better. The sweetness, again to my ears, is more important to the signal than any other component. It seems to make the entirety of the sound more coherent and "like it is supposed to sound".
