I tried this next to the Boss OC-3 and loved this pedal way more. It didn't give me that super "processed" sound that you can sometimes get out of a pedal of this nature. The Behringer model has sounded great so far! Not bad for $25.
I've bought this one after my very positive experience with the Behringer DD400, but they couldn't be more apart. It's kinda useful for some riffs I made and played, but it is just bad quality in the making.
I use it every now and then in some songs but that is about it.
I tried this pedal before, and though I loved the octave effect it gave to me BUT what really bothered me was the "crispy-radio" noise on the amplifier that was killing absolutely the effect. I wasn't using the best amplifier and bass (because I use it on bass) so I am willing to try it again with a decent rig and see how it works and make another update on this review.
