Chromatic Tuner for Guitar & Bass

More Info

Needle-Accurate Metering

In the tradition of its top-selling TU-12 predecessor, the new TU-12EX offers needle-accurate metering for precision tuning, including high-visibility sharp and flat indicators to ensure perfect tuning. Never play out of tune again!

Built-In Mic

The TU-12EX offers two forms of input: a line input or the built-in microphone. Plug your electric guitars and basses into the Line input, or simply point the built-in mic at acoustic guitars or other instruments that aren’t equipped with a pickup. It’s super convenient!

Drop-Tuning Support

For guitarists who drop-tune, the TU-12EX offers a special Flat Tuning mode, which lowers the pitch in user-defined semitone increments. The range can be set for up to six semitones.
