dbx 166xs Stereo Compressor [Found to be defective, sold as junk]

dbx 166xs Compressor with Power Cord

Upon regular inspection, a defect was found, so this item is being sold as junk.
During inspection, it was found that the Stereo Couple button in the center is unresponsive. (Switching is not smooth. This may not be an issue for those who do not use this button often.) Therefore, please consider this item as junk.

Shows signs of use (dirt, scratches, rust, etc.).
The right rack ear is slightly bent.
I purchased this used but have not had the opportunity to use it. I only confirmed that it powers on and produces sound; I have not performed other detailed checks.

If minor details are a concern, please refrain from purchasing.
