This is a cute, design-focused Klon-style overdrive. The sound quality is superior compared to other Klon clones, and it was one of my favorite pedals because it brightened up the look of my board. There are no operational issues. As shown in the picture on the back, there are traces of tape. -------------------------------- A transparent overdrive based on the Klon Centaur circuit. It features an OD switch for smoother sound shaping. True bypass.
