I hate to sell my OP-1, but I honestly don’t use this anymore. I only bought this for the portable 4-track recorder, as I won’t use synths or drum machines in my music. I recently bought Zoom H6 for recording on the go, which is better suited for my use case. It’s missing the rubber footpad on the upper right (as seen in the pics). Otherwise, it’s in great condition. Comes with a power supply and a generic black case. I also have the original black box as well, which I can include in the order if you’d like. Message me with any questions or an offer.
