Used on the 90s as roberts main guitar, debuted on the "wish" album record and promo era

Mark Knopfler is known to use the Gibson Chet Atkins Country Gentleman guitar. This is evidenced by a photograph taken at the Chet Atkins Musician Days in Nashville on June 24, 1998, where Chet Atkins presented the guitar to Mark as a token of appreciation for his role in organizing the event. Additionally, a picture taken by Guy Fletcher at a soundcheck during the Shangri-La tour at the Ryman Auditorium in Nashville on July 13, 2005, shows Mark using the guitar. This event was in support of the Chet Atkins Music Education Fund, and Guy Fletcher noted, "On a couple of tunes, Mark and Richard used two of guitars which belonged to Chet. These came out of the Hall of fame for the evening." The images and details are sourced from a Premier Guitar article from November 2009.

Seen on cover of "Me and my guitars", Gibson made the Country Gentleman for Chet Atkins in 1987.

Isaak revealed in a 2002 interview with Acoustic Guitar that he uses a one-of-a-kind Gibson: "For my electric, I've got a one-off Gibson version of a Gretsch 6120, a sort of Chet Atkins thing. They made one of these things and gave it to me to see if I liked it, and I liked it so much I've been playing it ever since. People told me they thought it was a White Falcon, but it's not. It's just a white Gibson. I don't think they ever manufactured any of the things. They strung up this one prototype, scratched their heads, and said, 'Huh. Give it to Isaak.'"

Jorge Drexler can be seen using the Gibson Chet Atkins Country Gentleman as his main electric guitar during the "Amar la Trama" tour and sessions, as evidenced in the video "La nieve en la bola de nieve" on YouTube, published by Jorge Drexler.

In this interview, Fieger says.

"DOUG: I did take some lessons but they wanted to teach me stuff like "Lady of Spain" and I really wasn't interested in learning that single-note kind of square music. Not long after that I met a guy who lived across the street from me that was in a band. By this time I had gotten a Country Gentleman which was a really beautiful and expensive guitar. Well, he offered me a gig in his band if I would switch over to bass and let this other guy named John Corey play my Country Gentleman! (Laughs) I had to go out and rent a bass while this other guy was playing my guitar! Anyway, after that I became a bass player for the next fifteen years. I really never played guitar in a band until The Knack. John Corey and I went on to form a band called Sky that got signed right out of high school. We made a couple of records with Jimmy Miller who produced the Rolling Stones and Traffic."

So, link which says "Country Gentleman" leads to Gibson's product list, where Country Gentleman is shown. So, that is Gibson, not Gretsch Country Gentleman.
