Sonic Research Turbo Tuner Mini ST-300

Sonic Research Turbo Tuner Mini is the fastest and most accurate tuner for guitar and bass. The display on the Turbo Tuner is a true stroboscope. You can see from the screen the difference between the input signal and the Turbo Tuner's internal reference frequency. This ensures quick tuning and extreme accuracy.

The race for the fastest and the most accurate guitar tuner in the world has been intense for several years. As I was delving into the temperament of guitars, the inventor of the True Temperament -system, Paul Guy, praised the Sonic Research Turbo Tuner. I tried the tuner already in 2009, but I thought that its user interface was too confusing. Those days Juha Ruokangas had ordered a small batch of Turbo Tuners to himself and sold them to his guitarist friends. They all praised the tuner for its speed and accuracy.

Introduced in 2014, the Turbo Tuner Mini was a revelation to me. The interface is ingenious, the pedal is small and elegant, the enclosure is durable and its operation is even more accurate than in the older models. I’d never have thought, that Peterson would be overthrown – live and learn! (Kimmo Aroluoma)
