This is not the only Octavio pedal in Jim Dunlop’s roster – there’s currently a mini-sized Jimi Hendrix Octavio fuzz pedal with selectable octave – but it is the only one available as a standard two-knob MXR pedal without any artist connection. 

And while there are no Hendrix graphics as seen in a previous same-sized MXR version, the lineage can be traced back to the vintage pedal used by Jimi to full effect on Purple Haze. This is silicon fuzz with a gritty edge and that upper octave harmonic bedded into it.
