About Bass E♭ Standard
Every string sits a half step below E Standard: E♭ A♭ D♭ G♭. Downtuned standard tunings keep every chord shape you know; songs simply sound lower and the strings feel a bit looser.
Bass E♭ Standard matches guitarists who tune down a half step. Every string drops a half step, so all your fingerings stay the same.

Low notes. The lowest string here is E♭1 at 38.89 Hz. Most phone mics lose a lot of level below 80–100 Hz, so they mostly hear the string's overtones. If the reading jumps, play the 12th-fret harmonic with the ×2 harmonic mode, or plug in through an audio interface. That's physics, not you.

How the tuner hears E♭1

String tension
Strings and tension
Strings 4–1: about 11% less tension (approx., same strings, same scale length).
Most players keep their usual strings for this. If the lowest string feels floppy or buzzes, go one gauge heavier on that string only.
