Comments: Fender switched back to the Blackface era cosmetics some time in 1980. Pro Reverbs produced between late 1980 and 1982 have a black control panel and Black / White / Silver grille cloth. A Boost switch, master volume, and hum balance control was added before the Pro Reverb was discontinued.
