Tired of imprecise tuners, those that never settle and fail to pick up the signal optimally? Look no further, here is the Sonic Research Strobe Tuner!

The Sonic Research ST-300 Mini is nothing less than the best tuner on the market and the only true strobe tuner available. In an ultra-compact format, it is powered by 9VDC with only a few mA. Very clean manufacturing, quality case, PCB and component at the top, it's micro pedal has been a reference for many years, that no other alternative has managed to dethrone. Purists will tell you, nothing equals Sonic Research.

The difference with all other products of its kind? Its speed, accuracy, readability and reliability over time.

What we have:

- Real strobe tuner in mini-pedal format

The Turbo Tuner's ring of LEDs is a true stroboscope. The LEDs are driven directly by the analog input signal and electronically triggered, showing the true stroboscopic effect by comparing the input signal and the internally generated reference frequency. This gives instant response and pinpoint accuracy.

If you are looking for the top of the top of the tuner, the Sonic ST-300 is THE benchmark of its kind and will be for many, many years.
