This late 70's Deluxe Reverb has undergone the blackface conversion, and sounds excellent. These can easily hang with their 1960's counterpart, and at a fraction of the price. Cosmetically it shows minor signs of previous wear, and has added wood screws to fasten the grillcloth panel to the baffle. Internally, it has replaced electrolytic caps, along with the parts for the blackface conversion (including the subtraction of the boost circuit), and a couple replaced power resistors. Also there is a mid knob installed on the back of the amp, in place of the normal fixed resistor.
