Classic C.O.B. octave tones!
This easy to use fuzz box will transport you to new lands with blissful sonic exploration!
Based on the sought after Prescription Electronics C.O.B. pedal, the Argo delivers classic, vintage octave tones.
The Argo gives you a boosted clean tone, a fuzz octave tone and a blend control to dial in the perfect amount of filth.
This fresh take from Mythos also plays well when plugged into a drive pedal for a smoother, more subtle effect.
The pedal runs the gambit of classic octave fuzz tones (think Hendrix, SRV, Doyle Bramhall II and more).
Like most vintage octave boxes, the Argo reacts best with single coils above the 10th fret (rolling back your volume helps the octave jump out as well).
