Decade Overdrive effector for achieving a variety of tones. Only lightly tested indoors. The switch was pressed by hand. - Model Name: Decade Overdrive - Controls: Bass, Treble, Volume, Gain - Manufacturer: The Amp Shop Nishida Seisakusho - Power: DC 9V - Accessories: Main unit, box, bag From the time of purchase, there were traces of what appears to be spray or water droplets on the surface and top of the case. I tried wiping it with alcohol, but it didn't come off. (See photos 6-10) Thank you for looking.
