E.F. 12-String

In "The Wreck of the Edmund Fitzgerald" Gord uses an epco, I believe.
("Don't beat me down" if I'm wrong).
After the verses "twas the witch of november come steelin" and "the church bell chimed till it ran 29 time for each man on The Edmund Fitzgerald" there is a high pitched guitar sound. Is it the same one Gord is using or is it a different instrument? Also, you hear it in the last verse in "All the Lovely Ladies".
If anyone know please let me know, my curiosity is overwhelming.

The Gibson B45 has a very distinctive sound that's easy to pick out of a mix -- more of a thick body to the sound than most jangly 12 strings.

Gord has often used a "high string guitar" in recording -- basically a 6 string that's using the lighter octave strings of a 12 string.

In "All the Lovely Ladies", Gord is playing his usual 6-string, while Terry plays his regular 6-string in one speaker, and Red plays the "high string" guitar in the other. The "high string" can be heard in other songs like "Patriot's Dream", "Ode to Big Blue", "Never Too Close" and "Don Quixote". The rhythm guitars in "Summertime Dream" are two high-string guitars, one in the left channel adn one in the right. Gord also plays high string guitar on "I used to be a Country Singer". The high strings, when panned hard right and left and played together sound remarkably like a 12-string.

I'll have to listen to these songs because I've never notices it before.
