The Naga Viper is a booster that lives in the grand old tradition of the Dallas Range master Treble-Booster. The original Range master has been used by many influential British guitarists including Tony Iommi, Brian May, Marc Bolan, and KK Downing and Glen Tipton of Judas Priest. These guitarists, while completely unique in their styles, share the Range master as the secret of boosting their cranked British tube amps into a juicy, harmonic-laden rock tone that always cuts through the mix and is ultimately proto-metal.
