9V VOLTAGE SAG UTILITY Since the fuzz effect was invented in the early sixties, guitar players have gone to great lengths to achieve the perfect fuzz tone. Apart from many mythological methods, there's one trick that always works: use a dying battery. Inherently simple devices like fuzz circuits are extremely sensitive to the amount of voltage that they receive, thus any change in the voltage from your power supply will cause drastically different tones. In order to achieve that with the Volture, simply place it in between your power supply and your pedal, and you can precisely trim the input voltage and perfectly replicate the tone of a dying battery. Though JHS developed it specifically for vintage fuzz circuits, the Volture will work on any fully analog pedal. In fact, you might be surprised by the trippy sounds you find lurking in your favorite overdrive or distortion.
