To my ears the 1977 show is all Mighty Mite at least in Franky and the 1979 tour at least in Osaka sounds more like a PAF or slightly overwound PAF because it is warmer and the attack is slightly softer, it still has some nice crunchy raunch to it but it doesn't have as much of that obscene ratty, fuzzy like, crunch that the 1977 recording does. I would say for the Osaka show it could be any PAF type from slightly overwound to the early Duncan JB with the coil mismatch and in the 13-14K resistance range as I think Ed may have been trying to get away from using the MXR or Boss EQ pedals to tighten things up and boost for solos.
Remember the two big Colorsound metal footswitches on Ed's board were looper pedals for the MXR 6 band and the Echoplexes according to Robin L and that makes a hell of alot of sense because at times it's kind of obvious Ed has more gain and punch for the solos even live.
