How to tune a bass online
Press “Tap to tune” to start the tuner and allow microphone access when asked. Pluck one open string and let it sustain so the tuner can lock onto the pitch. You will see the note name and whether the string is flat or sharp. Turn the tuning key a little, then pluck again to confirm the change. Work through each string until the display settles on the correct note. When you finish, do a quick second pass to confirm everything stayed in tune.
Choose 4-string or 5-string and follow the right notes
Use the string selector to switch between 4-string and 5-string bass setups. The target notes update automatically, so you can tune standard E A D G on a 4-string, or include the low B for a 5-string. If your bass is set up differently, start by matching the closest standard tuning, then adjust each string to your preferred notes. This helps the tuner recognize pitches more reliably, especially in the lower range. Once selected, your choice stays consistent as you continue tuning.
