This clip demonstrates the Naga Viper into a fully cranked Princeton Reverb to obtain an old school English heavy metal sound. Very good.
The Naga Viper is Catalinbread's extension of the famous Rangemaster treble booster. Two additional controls enable continuous control of bass response and gain.
The first segment is recorded using an iPhone's built-in microphone; you will notice some mic distortion as it is aimed close to the amp, don't worry! The second segment features the audio recorded through a top quality recording chain (Royer R121, Langevin DVC, Lexicon PCM91, Pro Tools).
