Original issue - from the 70's I'd guess. The box shows that it's been used over the years so if you're looking for an aesthetically perfect unit this ain't it. BUT if you're looking for THAT SOUND then it's all here. It works perfectly, never had any problems at all. Literally plug and play. Echo/Chorus slider works great, as do the foot switch and all three original knobs. Also comes with a built-in AC power cord that's in good shape.Really hate to see this grail piece go but I've got too many vintage analog delays and this thing sounds too good to just be sitting on my shelf.
