About Jesus Just Left Chicago
Jesus Just Left Chicago is the slow blues on Tres Hombres (1973) that follows Waitin' for the Bus without a break. Billy Gibbons takes it at a crawl, with long bends and space between the phrases, and the rhythm part is in E Standard on the tabs.
This is the song that does not match its album. TuneLit measured Tres Hombres at concert pitch (+3.5 ¢), but Jesus Just Left Chicago about 24 ¢ sharp (A ≈ 446.1), on both the 1987 remix CD and the 2006 remaster of the original mix. It has its own Tune button, set 24 ¢ up. With the album's setting, a guitar would sit almost a quarter of a semitone flat of the record, which is plain to hear in a slow blues full of held notes.
Two things trip players up. First, the segue: Waitin' for the Bus runs at concert pitch and this song about 20 ¢ higher, so play along with the pair and you must retune between them or pick a middle reference. Second, the most-viewed lead tab lists a strange tuning with the A string lowered to G; the rhythm tab and the record fit plain E Standard.
Tip: Use the song's own +24 ¢ button, not the album's, and check it on the first long bend.

- Turn String 6 to String 1 until each shows ✓ in tune. Jesus Just Left Chicago sits 24 cents sharp on the record: at A 440 your guitar would sound that much flat against it, which Tune already corrects.
- Then play Jesus Just Left Chicago along with the record: its lowest open note and your String 6 should ring together without a wobble.
