Behringer UO300 Ultra Octaver Good pedal with a nice sound that really deepens the sound. We use it to make a sort of moody bass sound, sort of like "I heard it behind the grapevine", but with a more double bass sound. Its too bad these behringer pedals have plastic covers, it makes them just feel a little cheap, I wish they would use metal, if they can still keep the price at a reasonable level. Overall we are happy with this pedal and the sound that it produces.
Not used it enough to give a expert review, but not as good as I hoped for on first use. Will spend more time with it and hopefully get more out of it
