Comments:

  • The AA1069 schematic shows a Mid control but it did not get installed on producion models.
  • 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 silver sparkle grille cloth.
  • A Boost switch, master volume, and hum balance control was added before Pro Reverb was discontinued.
