John MayerandShawn Mendes’mentor/mentee relationshipcontinues to evolve.

Speaking toZane Lowefor Apple Music, Mayer revealed he and Mendes often trade tracks they’re each working on to get each other’s feedback.

“We send each other everything we make,” Mayer, 43, tells Lowe on Wednesday’s show. “It’s really cool. As I sit here, I know what he’s going for on his next record — which I find actually really informative for me as a musician to understand. If I can understand where the key players are going, it helps me understand where I would sit, given the records I make.”

Calling 22-year-old Mendes “remarkable,” the guitarist — who drops his upcoming album,Sob Rock, on Friday — says he and the “Wonder” singer don’t hesitate to share their thoughts with one another.

“He’ll send me stuff he’s working on, and I’ll send him stuff I’m working on. And we don’t really sugarcoat it for each other,” explains Mayer. “Sometimes we go, ‘Cool.’ Sometimes we go, ‘Nowthat’sone.’ He is so honest.”

Mendes' steadfastness is reminiscent of a certain Beatle, the “Last Train Home” singer tells Lowe.

Mendes — a longtime fan of Mayer who first met the guitarist in 2016 — has been equally effusive in the past, designating Mayer as “a dude I can call.”

“He’s one of my really, really good friends,” Mendes told PEOPLE in 2018. “The most incredible thing I learned from [him] is that no matter how much experience you have, you never are done learning; there’s always something to be learned.”

He continued, “John will send me new music and ask me what I think. When that happened to me the first time, I was so impressed that he didn’t see himself as a master yet. He’s always trying to learn and wants to get better; he always wants to grow with the people and not get left behind.”

“He’s a badass,” added Mendes. “He’s just so smart and intellectual. He has a very interesting view on the world — a view I’ve never heard from anyone else.”
