Comments: * Some of the PRO RVB AA1069 Circuits (Silverface with the Mid control) came with a solid state rectifier. * 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 Pro Reverb was discontinued.
