Tuning your bass to Drop B

Automatically with the microphone, or by ear: tap any note on the headstock to hear a real recorded reference.
  1. 1

    Allow microphone access. For the most accurate reading, play close to the microphone and pluck firmly.

  2. 2

    Play one string and let it sustain. Low notes take a moment longer to read, so hold the note.

  3. 3

    Tighten the string if you're flat (needle left), loosen it if you're sharp (needle right).

  4. 4

    Tip: the 12th-fret harmonic is an octave higher and often gives a steadier reading on the lowest strings.

Questions & troubleshooting

What are the notes of Drop B tuning?
Drop B tuning on bass is B F♯ B E, from the lowest string to the highest.
How do I tune to Drop B from standard tuning?
Starting from standard (E A D G): string 4 down 5 semitones, string 3 down 3 semitones, string 2 down 3 semitones, string 1 down 3 semitones. Every other string stays the same. Use the tuner above to check each string.
Do I need different strings for Drop B?
Not necessarily, but when strings are tuned down a long way they lose tension and can buzz or feel floppy. A slightly heavier string gauge keeps them stable and in tune.
Is Drop B tuning bad for my bass?
No. Changing tuning is completely safe. Just tune gradually, and when raising pitch go slowly so you don't over-tighten a string. After a big change, the neck can take a day to settle, so check your tuning again.
