Slash has joked he's a "very private noodler" when it comes to experimenting with his guitar.
The former lead guitarist of Guns N' Roses is famed for his impressive instrumental abilities. However, Slash isn't satisfied with his skills and regularly uses his down time to improve.
"Playing guitar is what I do and it's what's been driving me through hell and high water for the best part of 30 years. I don't know how to put it without sounding pathetic but I'm still madly in love with trying to get better at the guitar and making things happen with it," he told Kerrang! magazine.
"I sit and noodle on the guitar pretty much all the time but I don't drive people to distraction because I'm a very private noodler.
"I'll noodle on the bus or in the dressing room or in a hotel room but I'll do it quietly because I don't necessarily like people hearing me practicing or working new stuff out. I don't noodle obnoxiously!"
Slash's other passion is horror movies.
The star has his own film production company called Slasher Films, and hopes to put the "tension" element back into new releases.
"The movies coming out in the '60s, '70s and early '80s had a psychological edge that would really grab you by the short and curlies," he explained. "The gore factor can sometimes be used to cover up the fact that there's really nothing else there. Even though it's called Slasher Films, it's the antithesis of the slasher gore ethos. It's more about the tension and the drama of what makes things scary than it is about splatter and dismemberment."© Cover Media
