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 FZ-2 is a fuzz which people have asked for a re-issue of for many years since it was discontinued in 1997. The Super Fuzz is an almost exact copy providing all of Univox Superfuzz style glory and classic fuzz tones but also a HUGE modern fuzz wall of sound style fuzz which once experienced can take days to recover from!
Then there's the secret mode! Unique to the Behringer, jamming the switch between fuzz 1 and fuzz 2 initiates both circuits providing one of the most BRUTAL tones ever heard by man-kind. To hear this simply select the Strandberg guitar and hold on for dear life!
