Sometimes a song just needs a certain guitar, and that was the case with Hozier and his hit “Jackie and Wilson.” He originally wrote the demo in the key of E, but it was too high for his voice. This Gretsch G5265 Jet Baritone came into his life and quickly helped morph the song into what you hear on the radio. He keeps it tuned to B–F#–D–A–E–B and uses a mixture of D’Addario strings. The B & F# strings are EXL 145 (.016 & .020) while D, A, E, and B strings are EXL156 (.034, .044, .056, .072).
