I bought this two weeks ago and have used it 3 times in my practice space. I have everything that was in the box, including the warranty card, there is not a scratch on it. I chose this simply because I needed the Envelope Filter and Octave functions and it was cost effective. This unit does sound incredible, but is WAY more than I need and I simply prefer pedals. I am valuing the B3 at $180. I would like to trade it for an MXR M82 Bass Envelope Filter and MXR M288 Bass Octave Deluxe. Both MXR pedals seem to sell used for between $80-100 here on TB, so I feel that these two MXR's for a brand new Zoom is reasonable. All I care is that the pedals function. I don't care how chipped up they are.
