Tune your bass in seconds

A precise chromatic tuner that listens through your microphone and guides you to standard EADG tuning. Works for 4-string electric and acoustic bass guitars.

Optimised for low frequencies

Bass guitars start at E1 (~41 Hz). Our tuner uses an extended FFT buffer specifically to track these low frequencies without octave errors.

Works with DI or mic

Plug your bass into your computer through an audio interface for maximum accuracy, or use your laptop microphone for quick tuning.

Chromatic for any tuning

Drop D, D standard, E♭ — the chromatic detection handles every tuning. Just follow the cents readout.

How to tune

Standard bass tuning

4th string (thickest) — E1 (~41.2 Hz)

The lowest E on a standard 4-string bass. One octave below the guitar low E.

3rd string — A1 (~55 Hz)

A perfect fourth above E.

2nd string — D2 (~73.4 Hz)

Another perfect fourth up.

1st string (thinnest) — G2 (~98 Hz)

The top string. A perfect fourth above D.

Common questions

FAQ

Why is my low E not detected cleanly?

At ~41 Hz, E1 sits near the lower limit of most laptop microphones. Plug into an audio interface if possible, or pluck firmly and mute other strings.

Does this work for 5-string bass?

Yes. The chromatic detection picks up any pitch. For the low B string (~30.9 Hz), you may need an audio interface since the microphone bandwidth may not capture it cleanly.

How often should I retune?

Check tuning at the start of every practice session. Bass strings hold tuning better than guitar strings but still drift with temperature, humidity, and playing intensity.
