Sweet Home Chicago

Robert Johnson · Vocalion 03601 (single); later King of the Delta Blues Singers · 1936

There is no amp and no pedal here — "Sweet Home Chicago" is one man with a small-bodied 1930s flat-top acoustic, one microphone, and a disc cutter in a San Antonio hotel room. The documented sound is a boxy, midrange-heavy guitar with a hard thumb bass and clipped treble notes, wrapped in 78 rpm bandwidth limiting. Which guitar it was is genuinely disputed: a Gibson L-1 and a Kalamazoo KG-14 are both credibly argued, and the first-day session may involve a different instrument than the later dates.

Where these numbers come from: worked out from the documented rig and the sound of the record

Tuning

Standard tuning, no capo · Capo at fret 2

The 78 plays in F#, and the standard reading is standard tuning with a capo at the 2nd fret using E-shape fingerings; if you use a speed-corrected transfer (which lands a half step lower, in F), move the capo to the 1st fret.

Part: Rhythm

Guitar

  • Gibson L-1 (small-body flat-top acoustic)
  • Kalamazoo KG-14 (small-body flat-top acoustic)

Amp

None — unamplified acoustic guitar

Cut November 23, 1936 in Room 414 of the Gunter Hotel, San Antonio, with one microphone straight to a disc-cutting lathe; Don Law produced and Vincent "Vinnie" Liebler engineered, and Johnson reportedly moved the mic stand and played facing into the corner of the room.

Only for players covering this on an electric or through an acoustic amp — the record has no amplifier at all; keep it just shy of breakup, scooped of deep bass, and roll off the extreme highs to mimic the 78's bandwidth. The instrument itself is contested: the famous studio portrait is usually read as a Gibson L-1, while the small "cigarette" photo is widely identified as a Kalamazoo KG-14, and a 1961 Frank Driggs letter to Don Law indicates Law borrowed a guitar after Johnson's arrest, so the first-day sides (including this one) may be a different instrument from the November 27 sides.

Tone character

dry small-body acoustic · boxy forward mids · thumping fingerpicked bass · limited highs, no sparkle · room-corner slap and ambience

medium

The rhythm part is a thumb-driven boogie bass line under E-shape chords with a capo, so the hard work is keeping the shuffling thumb steady and independent from the treble stabs and the stop-time breaks.
