Solo · reviewed by the Change Your Strings editorial team ·

Buddy Guy's guitar tech confirmed on Premier Guitar's 2011 Rig Rundown that his strings are plain Ernie Ball Slinkys at .011 to .048, the Power Slinky gauge, changed frequently since his aggressive attack wears out the high E within a night. He plays Fender Stratocasters through two custom Chicago Blues Box amps built to a Bassman voicing, with his own Dunlop signature wah and an Ibanez Tube Screamer ahead of the amp.

Who Buddy Guy is

Buddy Guy is a Chicago blues guitarist whose career runs from session work at Chess Records backing Muddy Waters and Howlin' Wolf in the 1960s through his own decades-long solo career. Younger guitarists who came up idolizing him, Eric Clapton, Jimi Hendrix, and Stevie Ray Vaughan among them, have long cited him as a direct influence on their own playing, alongside Chicago blues contemporary B.B. King.

Per Guitar World's account of the record, his 1991 album Damn Right, I've Got the Blues is generally regarded as his commercial breakthrough, reintroducing him to a mainstream rock audience decades into his career. Per Wikipedia's sourced biography, he has continued releasing records and touring since, including Born to Play Guitar (2015), and received a Grammy Lifetime Achievement Award that same year.

Why this fits his sound

Guy's tone is built on attack, not gain. A Bassman-style amp gives him headroom and a clean-to-slightly-dirty edge rather than a saturated lead tone, so the aggression in his playing comes from how hard he hits the strings and how he works the wah, not from a wall of distortion. That same aggressive attack is why his tech says the high E string routinely needs replacing between shows: a lighter, plain Slinky set under a hard-picking hand simply does not last as long as it would under a lighter touch.

The Tube Screamer ahead of the amp adds midrange push for solos without turning the amp into a high-gain rock tone, keeping the Bassman-style clean headroom as the foundation. It is a simple, road-proven chain: guitar, wah, overdrive, amp, built to survive nightly touring rather than to chase a studio-perfect tone. Our E standard tuning guide covers the gauge and tension tradeoffs behind a plain Slinky set like his in more detail.

Plain nickel-wound Slinkys at the Power Slinky gauge. Guy's aggressive attack wears through the high E fast enough that his tech changes it nightly, and the rest of the set gets refreshed frequently to keep pitch and tone consistent under heavy bends and vibrato.
