The pedal industry as a whole revolves around several different circuits and their variations, some companies work hard to break the boundaries such as the likes of TC Electronic but most companies look at what sells and add their own spin/USP to the products.
With Behringer, USP is often price, but with some of their pedals, it's available! You see some of the clone pedals Behringer makes are no longer available from their original manufacturers and the second-hand prices can be silly. The BOSS OD-2 is a current production pedal that the OD200 replicates. What's really cool about this circuit is the mode knob which at one end is a full mid push overdrive tone and at the other end is a more mid-scooped distortion type tone. The beauty of this is the in-between tones which allow for so many great normally unheard flavours.
