DR Pure Blues 10-46 on the Gibson Firebird is Johnny Winter's documented blues-slide rig — Winter, the Texas blues lightning-fast albino slide master, used the Firebird primarily for slide work in Open D / Open G tuning, paired with DR Pure Blues pure-nickel roundwound strings (.010-.046). Winter ran this combo across his definitive blues recordings and into his Muddy Waters production work. As Equipboard documents his rig: "Winter uses DR Pure Blues strings with a .010-.046 gauge" + Jim Dunlop Johnny Winter signature slide.

Conventional wisdom: every Firebird thread defaults to Ernie Ball Slinky 10-46 or NYXL — generic nickel-plated steel for that bright Firebird mini-humbucker bite. Mismatch logic: DR Pure Blues are PURE NICKEL (vs nickel-plated steel) — a vintage 1950s alloy that softens the bright Firebird mini-humbuckers into the warm, woody midrange Winter needed for slide-blues phrasing on tracks like 'Highway 61 Revisited' / 'Mojo Boogie'. Pure nickel + slide = the exact tonal recipe that gives Winter's Firebird a Telecaster-like blues warmth instead of the metal-mini-humbucker crunch.

Best for Firebird players doing slide blues in Open tunings; skip if you bought the Firebird for hard-rock metal-mini-humbucker bite.
