The Vintage Super Delay has the same functionality as the EMPRESS "Super Delay" (the normal, white version), but with a significant upgrade to the Tape mode sound. It's a limited edition model that has been modified to provide a deeper sense of compression and saturation, thoroughly pursuing the sound of dirty heads and slightly wavering, realistic sounds of vintage tape echoes. I purchased it new and have been using it. A general-purpose adapter is included. It's rarely seen these days. High sound quality.
