A precision bow straightener for violin bows that stabilizes and preserves correct bow shape, improving tone consistency and expression during practice and performance. Key benefits - Corrects and maintains bow curvature: Adjustable-width clamp keeps the bow at the proper camber to prevent warping and uneven tension. - Improves playability and expression: Holding the correct bow shape helps develop consistent bowing technique and dynamic control. - Reliable and portable: Lightweight construction and simple operation make it suitable for rehearsal, lessons, travel, and live performances. Features and specifications - Adjustable width: Fits a range of violin bow thicknesses by changing the clamp spacing for a secure hold. - Materials: Durable ABS plastic body with steel components for strength and long-term use. - Double-rail design: Two parallel rails increase stability and alignment when clamping the bow. - Grooved plastic clamps: Clips with grooves provide a firmer, slip-resistant grip and make installation quick and repeatable. - Comfortable and easy to use: Low-profile, lightweight design for fast setup and convenient transport. Practical applications - Concerts and recitals: Quickly straighten bows backstage to ensure consistent tone and response during a performance. - Practice and lesson sessions: Use as a training aid to maintain correct bow camber between lessons and reinforce proper technique. - Instrument care and storage: Apply periodically to preserve bow shape during short-term storage or while traveling. How to use (brief) - Adjust the width to match the bow shaft. - Position the bow in the grooved clamps between the double rails. - Secure the clamps so the bow is held gently but firmly. - Leave in place for short-term shaping or transport as needed. What you get - A compact, adjustable-width bow straightener constructed from ABS and steel, with a double-rail frame and grooved plastic clamps for stable, convenient use. No special setup required — suitable for violinists who need a simple, effective tool to maintain bow shape, support consistent technique, and protect the quality of their performance.
