This newest version of the Naga Viper (early 2024) features an attenuator (ATTN) knob which acts like a level control for everything in front of the Naga Viper, letting you shave some heat from the incoming signal before it runs through the proverbial gears of the booster. This leads to less saturation and undesirable effects and more treble-boosting goodness going into your amp. The transistor in the Naga Viper has also been replaced and the circuit tastefully reworked to accommodate players of all stripes. Some players will leave the Attn control all the way up, and this design choice is for them. By swapping out the transistor, the Naga Viper is even hotter than before, with extended ranges for both Heat and Boost controls. Diming both controls now gives a slight edge compared to V1, opening up the range of the attenuator as well. The Naga Viper MKII supports standard DC power supplies from 9 to 18 volts or a 9V battery. Controls "¢ Heat: Gain knob from classic treble booster response, slightly dirty boost, up to an actual drive. "¢ Boost: Significantly higher output level allowing to get more from even the most stubborn amps. When turning this knob, it is normal to hear a whooshing sound, the original Rangemasters also did this. "¢ Range: Amount of bass frequencies let into the booster. As you roll this control down, more and more bass is let into the circuit and the range is thus increased. With the Range all the way down, you experience a full-frequency booster that also increases the level of gain. "¢ Attn (attenuate): This control lets you tame the incoming signal down to a lower volume, which gives the circuit a little room to breathe before it does its thing.
