This is the PRUSSIAN BLUE REVERB by One Control (ワンコントロール). I purchased it from a musical instrument store in 2022. Operation has been confirmed. It comes with the original box, and the rubber feet are already attached. I used it at home about 5 times and then stored it at home. It's in good condition due to the low number of uses, but there are small paint chips on the surface and what appears to be scratches on the back. Please check the photos, and if you understand that this is a used item, I would appreciate your purchase.
