Released in 1983. This was a groundbreaking product as the world's first auto-tuner to feature a needle-type meter. Its high accuracy and excellent visibility have made it a beloved classic among many guitarists even today.

In 1983, BOSS released the TU-12, the world's first automatic chromatic tuner. While it's commonplace now, the ability to automatically detect and display pitch was revolutionary at the time. Furthermore, the TU-12 boasted an accuracy of +/- 1 cent (1/100th of a semitone). Considering that the human ear can only distinguish pitch differences up to 5 cents, this tuner offered accuracy that everyone could appreciate.

The TU-12 combined a traditional needle meter with LEDs, allowing for quick and precise tuning even for small discrepancies. It also supported tuning acoustic instruments via its built-in microphone. This compact design offered accuracy, visibility, and ease of use. It was loved by professionals worldwide, from players to repair technicians and roadies, as the standard for tuners.

High-precision TU-12 chromatic tuner, ideal for guitars and basses.
