As one-half of Slipknot's twin guitar towers, Jim Root has been a driving force behind the band's crushing riffs and evolving sound for over two decades—and he’s not done yet. As the band celebrates the anniversary of their groundbreaking debut, #4 himself sat down with Guitar Interactive's Jonathan Graham to discuss revisiting early songs, chasing authentic tones on tour, vintage guitar obsession, potentially taking off the masks, and why the work never really ends.
Meanwhile, prog metal titan John Petrucci joins us to talk Dream Theater’s latest epic, Parēsōmnia, the return of Mike Portnoy, the latest additions to his Ernie Ball Music Man Majesty line and why he’s always game for another G3 tour if the call comes. Expect some deep dives into tone, technique, and a few surprises.
Also, from a derelict shop in London's West End to stages across the globe, Orange Amplifiers has stood as one of the most iconic names in British tone for nearly six decades—and for good reason. We chart the story of one of the UK’s most iconic Amp brands and check out some of their newest releases for 2025.
Plus, as with every issue, we review the latest and greatest guitars, amps, pedals and more.
