I recently purchased a used BOSS DD-3. It works fine, but when I plug in a cable, it takes about 3 seconds before I can use it – the light doesn't come on when I step on it. However, once it lights up, it works without issue. As shown in image 6, the screw-in part is missing, but this doesn't affect its functionality. This is a fairly old product, so I'm a bit wary of returns. I'd appreciate it if someone who understands this would be willing to purchase it without the possibility of a return.
