alternate temperaments for a vast array of string and wind instruments,
and Soft Rubber-lined jaws to protect your instrument's finish while offering a firm grip for maximum signal tracking.
The jaw of the StroboClip HD is greater than 1" (25.4mm) to accommodate a variety of instruments and mounting locations.
Early music and orchestral instruments can be tuned with ease.
