After Felder joined the band, he mainly played rhythm while Felder and Leadon, and then Walsh later on, played the lead. But Glenn did play the solo on his solo song "Smuggler's Blues" though that was after the Eagles broke up. I think he's underrated guitar player. He's a bit overshadowed with Felder, Bernie, and Joe in the band. Plus he gave some solos away, Joe played the slide solo in "Midnight Flyer" after he joined, and Felder would play the "I Can't Tell You Why" solo live.
