Elder Audio Manufactory of China produces a series of clones of Boss pedals, and they are distributed worldwide under a variety of brand names including GLX, Beta Aivin, Harley Benton, Boston, and Boss-Hog. The pedals are identical with each brand; only the label changes. Their CS-100 pedal is a clone of the Boss CS-3.

It’s a very close clone, basically the exact same thing as the Boss. It not only has the same circuit and controls, it also uses the same quality of components, including metal pots and jacks. Compare against the Behringer version (also called the CS-100) which is all cheap plastic, including fragile plastic pot shafts, and which uses SMT (miniature surface-mount) components, making it very difficult to mod. The Beta Aivin uses traditional through-hole components, and they are spaced apart on the circuitboard enough that modding is very easy. I even think some of the component numbers (e.g. C13) printed on the board are the same as the Boss.
