Chromatic Tuner for Guitar and Bass

This successor to the legendary TU-12 provides BOSS’ famous needle/LED indicators for fast, accurate tuning. Other features include Flat Tuning of up to six half steps, ACCU-PITCH with an audible beep, a reference tone, a built-in microphone for acoustic instruments and battery-saving Auto-Off.

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!

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.

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!
