LinoStrobe Pro chromatic tuner

Tune your guitar, uke, violin, … in fact any musical instrument with the speed, accuracy and comfort of true strobe tuning! Simply sound the note to be tuned; it will instantly be recognised and displayed prominently. The strobe ring around it shows through its rotation and color whether you're flat, sharp, or in tune.

Extremely accurate, in contrast to needle tuners that average out fluctuations.

Lightning-fast response instantaneously follows every nuance of intonation.

World-class automatic pitch recognition, reliable even for overtone-rich instruments such as the mbira.

Supreme sensitivity and a clear display - you can even tune from across the room!
