Catalinbread Naga Viper Booster
The Catalinbread Naga Viper is our take on the classic Dallas Rangemaster Treble Booster with added features allowing users to dial it in with any amplifier.
The Naga Viper is a booster that lives in the grand old tradition of the Dallas Rangemaster “Treble-Booster”. The original 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 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. The Naga Viper is hommage to this famous circuit. Beyond it’s basic tuning, the Naga enhances the classic circuit with the addition of two extra controls – Range and Heat. The original Rangemaster had just one control – Boost which everybody dimed anyway but essentially controlled the output volume. Our RANGE knob is a continuous control which allows you to go from classic treble-boost to a full-range boost and anywhere in-between – as the original could only function as a set frequency “treble-booster”. The HEAT knob gives you control over the gain level saturation, unlike the original which was fixed at maximum gain.
BOOST This control sets the output level of the Naga Viper. For overdriving amps or overdrive pedals, you'll normally want to set this control fairly high. You'll notice that as you turn this control you'll hear a slight whooshing or crackle type sound - this is normal and is due to the traditional Rangemaster circuit used for the Boost control.
HEAT This control sets the gain level of the Naga Viper. At full CCW, you will get a clean boost. At full CW, you will get the traditional Rangemaster response which is a slightly dirty boosted sound that doesn't sound that great into a clean amp but into an overdriven amp it is like magic! For dirty boosting, start with the Heat control turned all the way up and then back it or slightly if necessary to get the overdrive sound you are looking for. At full CCW, you will get a clean boost which works great as a "MORE" pedal, making your sound louder with a nice presence into either a clean or dirty amp. RANGE This control sets the frequency response of the Naga Viper. For the classic treble-booster response, turn this control full CW. If you are playing into a cranked British style tube amp, you'll get those famous sounds! If you and you could use some more fullness, turn the Range knob back until you get what you're after. This knob is particularly useful for dialing in a thinner sounding single coil guitar or if you are boosting a Fender style amp or an overdrive pedal such as the DLS MkII or CB30. With the Range set around noon, you'll and that the frequency response is fairly "fat" with a slight enhancement to the treble frequencies. As you turn the Range control CCW from noon, bass frequencies will start to get boosted as well
