Drawing inspiration from the legendary Dan Armstrong Green Ringer, the Octave Master is dialed in to provide the most analog octave up available in this style of pedal. Its true bypass analog octave up dirty boost not only enhances your tone but also adds a touch of ring-modulated octave goodness, perfect for soaring leads above the twelfth fret using the neck pickup. Whether used standalone for spine-tingling octave tones or as a driving force for your other Fuzz/Distortion/Overdrive pedals, the Octave Master is a must-have addition to any Doom-inspired pedalboard.
