Nu–Fuzz designer Ed Sanner (of Fuzzrite design fame) was working on the new pedal as Mosrite filed for bankruptcy in 1969. Out of the bankruptcy sprang Sierra Electronics, a new partnership that would release the Nu–Fuzz, which was basically a Fuzzrite with a tone control. Sierra was forced to change its name due after a complaint from another entity called Sierra Electronics. The new name was formed via a simple combination of the names of owners Morris Rosenberg and Ben Sacco— Rosac.
