Considered to be the best of the oil can delays. Vintage 70s. If you’re looking at this, you probably know what it is. It powers up as can be seen in the photo by the illuminated power light. I plugged into it and the signal went through so the input and output levels work. What doesn’t work is the actual effect itself. So it is in need of repair. Also as seen in the photo, the power cord is a little bit sketchy. Should probably be rewired. Hoping it ends up with someone willing to fix it up. USA only, no international shipping.
