These adapters work perfect for almost any typical guitar pedal out there. Their universal application and cheap price makes them a very good bargain.
However, be aware that the part where the cable meets the adapter feels a bit fragile, I therefore wouldn't rely on these to last very long when kept moving around and handled too often. These work like a charm on my DIY pedalboard powered by an extention lead, where they can be kept in place. I doubt they would last very long if I would move them around as loose units though. Just something to keep in mind. Other than the fact that I'm a little suspocious about the part connecting the chord to the adapter, they seem very relaible.
