The Rolling Stones guitarist gave playing tips to the legendary axeman - who played in seminal 80s band Guns N' Roses and Velvet Revolver and is widely regarded as the best guitarist of his generation - when he was a child, but now the tables have turned.
Speaking on his Absolute Classic Rock radio show, Ronnie said: "Slash, I remember him as a kid spying on me when I was playing guitar and I'd teach him little licks, and now I'm learning licks off him, it's really good.
"He's a great guy to play with and he's a great at interacting, a good weaver, you know, we can weave, like me and Womack do and me and Keith Richards do. Slash is such a great talent, and he plays in my solo band when I take it out and he's on my new album as well."
However, Ronnie hasn't had as much luck teaching drummers to play the guitar, recalling one disastrous night when he tried to show former Beatle Ringo Starr and The Who drummer Keith Moon how to play.
The 62-year-old musician added: "I've got a funny story, back in 1974 when I had my studio in South West London, that Pete Townsend now owns, one night I had Ringo and Keith Moon down there and no drum kit, so they said, 'What are we going to do?' I said, 'Well let's all learn to play the guitar', So I taught them the chord of E, so we played just that one chord, E, all night, it was really funny."
Ronnie Wood's show on Absolute Classic Rock radio is broadcast in the UK on Fridays 6pm and repeated on Absolute Radio on Saturdays at 10pm.
