Catalinbread Naga Viper MkII
Catalinbread · pedal
The Catalinbread Naga Viper mkII is the second version of the Portland boutique builder's germanium treble booster pedal, offering an expanded control set compared to simpler treble booster designs. The circuit covers a range from clean treble boost through mild fuzz-like saturation, using germanium transistors to produce the warm, harmonic treble emphasis associated with 1960s British rock. A Range control adjusts the frequency spectrum from narrow treble boost to full-range boost, extending the circuit versatility beyond standard Dallas Rangemaster-type pedals. Best paired with tube amplifiers in blues, classic rock, and vintage British rock rigs.
