The Naga Viper is a booster in the grand old tradition of the Dallas Rangemaster "Treble-Booster". The Rangemaster 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 Rangemaster secret of boosting their cranked tube amps into a juicy, harmonic-laden rock tone that always cuts through the mix.

The Naga Viper is Catalinbread's version of this famous circuit and it enhances the classic circuit with the addition of two extra controls - Range and Heat. The original Rangemaster had just one control - Boost. The Range knob is a continuous control allows you to go from classic treble-boost to a full-range boost and anywhere in-between. The original could only function as a "treble-booster". The Heat knob gives you control over the gain level, unlike the original which was fixed at maximum gain.
