Online tuner for bass with microphone

On this page your can tune your electric or acoustic bass guitar or a double bass, using the microphone of your device. You can also tune by ear, using this page as a virtual tuning fork.

The fretboard above is interactive – you can click on frets to hear their sounds played.

The standard tuning for bass guitars and double bass is this:

  1. String 1 – G2, the highest (thinniest) string
  2. String 2 – D2
  3. String 3 – A1
  4. String 4 – E1, the lowest (thickest) string

It's the same as four lowest strings on a guitar, but one octave lower.

Tuning method: how to tune a bass guitar

Tuning a bass guitar is very similar to tuning a regular guitar, so you can check out our instructions for tuning guitars.

The common problem when tuning a bass with microphone tuners is that most microphones don't work well for low-pitch bass sounds.

To address this issue, try this:

  • Plug your bass into your computer and use its audio signal instead of the microphone as the audio input for the tuner.
  • If it's not possible, try using a high-quality vocal or instrument microphone instead of your built-in microphone.
  • Instead of tuning the open strings, hold a fret (try 5th, 7th, 12th). You will find the interactive fretboard above useful to see which notes should sound at each fret.

The same advice from above still applies, but the tuning itself is much more similar to tuning a cello – please check out instructions there.
