The vast majority of guitar players say that their pedals sound best when powered by an internal 9V battery. Unlike power supplies, batteries deliver ripple-free current, which translates into an absence of unwanted sound distortions and artifacts. However, 9V batteries have a short life and often die unexpectedly, their voltage sags as they empty and are a pain to replace.

Silent Power uses internal Li-Ion batteries and uses passive electronic circuitry to precisely regulate the output voltage, regardless of the batteries’ charge level. This is why Silent Power offers the same sound quality as 9V batteries do,┬ábut at the same time eliminates the problems associated with them.
