5Awesome in a different way...
By Jonny Sokko
I expected a precise pitch shift of my exact tone. That's not what you get. In my opinion, what you get is better. There is a slight tonal change and millisecond delay on the processed notes. The pedal performs pretty close to what you would expect when it is only partially engaged, but when you crank it to full shift in both directions, you get some amazing tones ranging from organ(ish) to synth-like to orchestral choir. If you want to sound like you are doing dual guitars like Thin Lizzy, then this isn't for you. If you want to add another incredible layer to your tone arsenal, then you've found it.

5Best Octave Pedal Ever
By Mr. Riot
The tracking on this mother is amazing. It handles two and three note chords well but sounds it's best with single notes. I'm mainly using this pedal to make up for the lack of a bass player being in a two piece band (guitar, drums). The bass sounds mean through a fuzz pedal and really puts out a full sound.

4Handy Effect, Not Perfect
By Cameron L. Mizell
I play guitar in an indie-rock band that uses synth bass instead of a bass player. We felt like some songs needed a little more low end, so I shopped around for an octave pedal and landed on the Octavius. In general it's a very handy effect not just for that indie-rock band, but also for a fattening up riffs and leads in other rock bands, or using the upper octave to create a cool texture on arpeggios.The main thing that sold me on the Octavius over other octave pedals was the added boost. I like a clean boost at the front of my signal chain to saturate my OD's, and this does the trick perfectly. The boost function is completely independent of the octave generator, so it's basically two pedals in one.The octave effect, in my opinion, isn't perfect. In my experience with all octave pedals, and this being no exception, there's a tiny bit of latency on the octave tracking. It simply doesn't respond the way you want your notes to respond on the guitar.I also noticed it having problems with certain notes. For some reason, when I play Ab on my D string, the octave cuts in and out, like it's having a hard time duplicating that one note. Same pitch on a different string, no problem. No idea why that happens, and it doesn't happen all the time, but it's noticeable on a clean signal.Also, as you turn the Master Mix knob up, your dry signal gets quieter as the octave signal gets louder. If you were expecting it to just add the octaves on top of your signal, that's not the case. And perhaps that's why they added the boost function.The Octavius sounds best in front of my OD and distortion boxes, partly because of the boost, but also because a little dirt masks some of that inauthentic response and any trouble it has with the tracking. For my needs, this pedal gets the job done, is built well, and is very transparent.
