INTRODUCTION
Welcome to the Catalinbread Naga Viper Boost!
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 our 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.
