Historical Context
The Fender Pro Reverb was part of Fender's Silverface lineup, produced from the late 1960s through the early 1980s. The Ultra Linear models from the late 1970s featured higher wattage and increased clean headroom, making them popular with players seeking powerful, pristine cleans. This era represents the transition between classic Fender designs and the more modern innovations that followed.
