Fender silverface twin reverb dating
Fender switched back to the blackface era cosmetics some time in 1980.
Twin Reverbs produced between late 19 have a black control panel and silver sparkle grille cloth.
Some players actually prefer these models, however, because they tend to compress more easily than any other Twin.
Turning up the channel volume allowed increased overdrive in the preamp section, with the overall volume of the amp controlled by the newly added master volume. But the engineers at Fender took it a step further, adding the ability to access more gain internally.Electronic components such as transformers, potentiometers, speakers, and some capacitors are often stamped with a date code, which indicates the manufacturer and the manufacturing date.The code follows the format: = a number from 1 - 52 indicating the week of manufacture.For whatever reason, the engineers at Fender added seven additional components to the output stage, effectively turning it into a semi-cathode-biased output.
While these amps were supposedly rated at 100 watts, they are nowhere near as potent as their predecessors.
In 1968 Fender changed to the “silverface” control panel.
