The Poly Blue Octave is fast becoming my favourite pedal! It was a slow burner for me, but once I sussed it, wow! It has so much scope and has allowed me to remove half my pedalboard.
It can cover. Synth, Analogue Octave down, Organ style POG effects, Chorus, Fuzz, Drive even Royal blood at a push, plus a myriad of other things. I might even get another one and have 2 on the board with different settings?
