Here's the product description: - There are quite a few small scratches. There are no major scratches or dents. - The "he" part of the "The Warden" logo is fading. - All knobs are heavy. They all turn from minimum to maximum, but the Release knob has a catch at the 10 o'clock and 4 o'clock positions. - The LED during operation is too bright, but this seems to be common in some batches and is not an abnormality. However, light also leaks inside the enclosure, so I've covered the LED protruding inside with insulating tape to prevent it from hitting the photocell (see photo 5). This affects the compression, so if you're concerned, you can easily remove it with tweezers. The default state is without the cover. - The product sticker on the back of the unit is missing. However, the manufacturing date and serial number are handwritten by the manufacturer on the inside of the back cover. - A box, manual, and cloth bag are included, but they are from a different unit. - The effect functions normally. By the way, the Level knob adjusts the overall volume (unity gain around 11 o'clock). The Sustain knob is the main feature of this pedal and functions like a preamp. At minimum, it has a flat tone, but as you increase it, the saturation increases. I think it can also be used as a booster depending on the settings. Please understand the above before purchasing.
