A very low tuning that needs a deliberate setup

Drop A places the sixth string at A1, with the upper five strings following E2, A2, D3, F♯3 and B3. It keeps a drop-style low-string relationship but is far below E Standard, so a light stock set is unlikely to intonate and feel correctly.

Choose a string gauge and setup designed for this tension before relying on the tuner. Work slowly from low to high, mute unused strings and let every note stabilize in the green zone before turning the next peg.

Four clear steps

How to tune accurately

  1. 1Fit or confirm a heavy enough string set for the scale length before tuning this low.
  2. 2Select A1 and lower the sixth string gradually while keeping nearby strings muted.
  3. 3Tune upward through E2, A2, D3, F♯3 and B3 one clear pluck at a time.
  4. 4Recheck all targets, then check intonation and neck relief with the completed setup.
Reference: A4 = 440 Hz
