This Super Reverb is in very good condition, and has a nice, strong presence to the sound. Being a 1971 amp, this is post-blackface circuit, but before they started with the pull boost on the volume pot. The power cord, reverb tank, & electrolytic caps have been changed, along with all of the coupling caps swapped for modern Orange Drops. Some resistors have been changed as well, but most of the originals remain.
