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 HM-2 is a distortion which people have asked for a re-issue of for many years since it was discontinued in 1991. The HM-2 has now been re-issued but until the HM300 was a great alternative that saw users getting all their Entombed style tones on a budget.
