This is a great sounding Fender Pro Reverb from 1978. Some of the features like the boost and Master volume has been disabled, which makes for a more blackface style operation and sound. While it does show moderate signs of wear it still looks good, with only a couple of blemishes in the tolex. The filter caps have been changed, along with various parts on the fiber board and control panel, giving it a mix of old and new parts. The end result is a great sounding amp with lots of clean headroom - see circuit pictures for further details.
