Steve Vai Reveals the Toughest Tone He Ever Had to Recreate — And It Wasn’t Van Halen

Legendary guitarist Steve Vai has opened up about the most demanding challenge of his career — and surprisingly, it wasn’t stepping into the shoes of Eddie Van Halen or tackling the complex style of Robert Fripp.

Over the years, Vai has taken on some seriously demanding roles. From performing Van Halen material alongside David Lee Roth to interpreting the intricate, progressive guitar work of Robert Fripp in Beat, he’s proven time and again that he can handle elite-level musical expectations. Yet, according to Vai, his biggest challenge came during his tenure with Whitesnake.

It was David Lee Roth who famously recruited former Frank Zappa guitarist Steve Vai for his solo band, convinced that Vai had what it took to rival Eddie Van Halen. In more recent years, Vai also faced the physical and technical demands of performing Fripp’s compositions.

Still, none of that compared to trying to match the tone of John Sykes.

“I realized it was harder to recreate his tone than anyone else’s,” Vai explained in an interview with Eddie Trunk.
“When he recorded those Whitesnake albums, everything just aligned perfectly. His songwriting, arrangement, and especially his tone — it was all exceptional.”

John Sykes, who also played on Thin Lizzy’s final album Thunder and Lightning, passed away last year. He contributed to two major Whitesnake records — Slide It In (1984) and the band’s self-titled 1987 album. Vai later stepped in for Slip of the Tongue (1989), taking over a role that was anything but easy to fill.

“His tone was incredibly thick and powerful,” Vai recalled.
“I tried to figure out how his harmonizer worked and how that width in his sound was achieved. It didn’t seem like heavy doubling, yet it filled so much sonic space. It was perfectly dialed in.”

Through experimentation, Vai came to understand that the newer iteration of Whitesnake needed its own identity. Instead of copying Sykes note-for-note and tone-for-tone, he chose a more creative direction.

“When we played his classic songs live, I used presets to widen the sound,” Vai said.
“But I have to give him credit — what he did on that record was incredible. His tone, feel, vibrato, note choices, and songwriting — everything was outstanding.”

Beyond his playing, John Sykes was also known for his passion — famously risking his life to rescue his 1976 Gibson Les Paul from a burning car. Often considered one of rock’s most underrated guitarists, he received tributes from bands like Guns N’ Roses following his passing. Steve Vai himself has long been among his admirers.
