I believe he is using an electric jaw harp. Makes a very interesting sound. Here is an example of a none electric one, just if your curious. https://www.youtube.com/watch?v=1myuIH9eAOc&ab_channel=Britain%27sGotTalent I have been fascinated with the jaw harp for a long time now.

Great selection. Still heard on classic rock radio daily! Interesting that this song was the B-side of "Love Hurts" on it's US release. Talk about a mega-single :)
