This Super Reverb was made by FEIC in April of 1964. It shows minor signs of wear and is still in very good shape. The grillcloth was changed, most likely in the 1970's, along with the reverb tank from a similar era. Internally, it has a changed power cord, fuse holder, electrolytic caps and trem optocoupler. All of the resistors and Blue Molded Ajax caps are still original.
