The only Behringer pedal I've been disappointed with. Very artificial and inconsistent sound. Seems to warble in and out of how much clean vs processed sound is coming through. I'd chalk it up to being a defective pedal but it seems to be a common complaint.

Could be Better, but it's £20!

So it does what it says on the tin. And that's about it. It's not horrible, but it does have some tracking issues. That said, it does everything it says it's supposed to, it works on guitar, bass, and keyboard.

I have not tried it with other effects yet, but hey, for £20, it's not terrible, yeah?

Not bad!

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.

Does your pedal make any noise when you have it ON on your amplifier? Not that normal noise every one does, but noise that can actually cover the effect and you got to struggle to hear it. Cuz mine did a lot

Eh.

Pretty standard Behringer material. Arguably poor tracking, but delivers decent tone especially with the octave 1 and octave 2 blended together. I end up using it mostly to deepen cheap keyboard voices into gritty bass sounds, but I haven't had great experiences using it with guitars or other stringed instruments.

The effect is perfect, the noise it did on the amplifier: TERRIBLE

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.

Ok and does it's job, but sometimes sound doesn't go through

It sounds good, but the audio gets cut out sometimes. Think it's a pedal problem, and not a guitar/cord/amp problem

Very limited

The sound from it is incredibly inconsistent-- sometimes it works, sometimes it doesn't, and you never know when it will.

Proportionally to its price

It's not the best octaver, I use it on my bass. The octave sounds a little artificial to me.

The not good, bad and ugly Octaver

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.
