Comments:
  • The speakers were arranged in a rhomboid patter with the top two offset to the left and the bottom two offset to the right. (70-81)
  • Bias mods and a hum balance control were added (AB568) and then removed. (AB569)
  • A "Boost" control and a master volume were added in the mid seventies.
  • Fender switched back to the blackface era cosmetics some time in 1980. Super Reverbs produced between late 1980 and 1981 have a black control panel and silver sparkle grille cloth.
  • A Mid control for the Normal channel and Line Out jack were added in ~1978.
