Fans of Octaver here is a peace ✌️ of cake an expensive one I got to admit but worth it. In my setup it is powered independently with the power adapter that came with the pedal to ensure a noiseless experience. The Lesly effect (and any setting) which can be use with an expression pedal is a big plus for me.

Um pedal bastante versátil, aflora a criatividade de quem usa. O fuzz então, é perfeito! Parece que tem um gate junto, pois elimina ruídos. Demorou um pouco para ser enviado, mas não muito. Enfim, melhor aquisição do ano, sem sombra de dúvida.

I love everything about this pedal, starting with the sparkle blue finish. This thing is ready versatile, with the ability to use your dry tone along with one or two octaves up and/or down. Each octave knob along with the dry tone can be adjusted to your desired level as each one has a dedicated knob which acts like a simple volume control for each respective octave (or dry signal). There is a mono button you can press to switch the octave effect between monophonic (the pedal works with single notes) and polyphonic (the pedal works with multiple notes, chords, etc.) so you have the choice there. There is also a fuzz button which applies some sweet fuzz to your tone. The only downside here is that you can't control the level of fuzz applied, but you can make adjustments to the tone and volume on your guitar to change the characteristic of the fuzz. Lastly they packed in a modulation knob which drives either their Phase 90 phaser effect, or a Leslie/rotating speaker effect depending which mode you have the pedal in (monophonic of polyphonic). So at the end of the day you are getting a very versatile octave pedal, a fuzz pedal, a phaser, and a Leslie emulator... all in a $200 dollar pedal. This one is a no brainer.

Nothing to dislike. It exceeded my expectations. I have purchased 2 other octavers (I won't mention the brands but one was cheap and the other not so much less in cost as this MXR Poly Blue Octaver but neither could touch it, no way! They would perform well on mono (unchoosable, really) but on any chords they are dreadful. I am mainly a rhythm guitarist and this MXR is incredible. The organ-like and bell-like effects open the door to inspiration and experimentation in my playing like no other pedal I've owned before and since I play alone, as many others do as well, it can add fullness and unbelivable dynamics to playing solo. I was gambling on laying out $200 for it but I am NOT sorry I spent it now. I've bought >200 even >100 guitars so 200 for a mere pedal seemed high but this is no MERE pedal. Sombody did their homework developing the MXR Poly Blye Octaver and it's worth the price of admission.
