Above is a noise gate. All look identical; the built, the knobs and even the model name of all 3 pieces is NG-100! Same goes for DS-100 and other pedals and even the 200 series, with slight changes in the design.
Actually, the reason for this striking resemblance is simple; they are the same. They are all from the same factory and all the parts are totally the same. What is different is the brand name that is badged on the pedals. Boston is the Beta Aivin of The Philippines. I am not sure about GLX though. And there are still many other names which I have not mention...
