It's incredible!
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.

Ho boy!
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.

Pedal excepcional
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.

Footswitch fallando
Gran sonido, pero el footswitch ha empezado a fallar a menos de 3 meses de comprarlo, no ha sufrido caídas ni golpes de ningún tipo, tendré que llevarlo a reparar
