Innovative guitar capo This is the world's first guitar capo with a built-in compression spring in the string pad (the rubber part that touches the strings). This design eliminates the tuning issues and pitch inaccuracies that frequently occurred with conventional products due to overtightening. We succeeded in dramatically reducing it. The simple yet elegant design, free of unnecessary elements, will enhance the beauty of your guitar. Triple Mechanism Capo (3 mechanisms): Spring pad, ratchet arm, and fine-tuning screw provide precise tuning and easy operation. ■Spring Pad: The automatic fretboard radius-adapting pad has nine small compression springs inside. This allows it to perfectly and automatically follow any guitar fretboard radius (185, 305, 400 mm, and even compound radii). It prevents certain strings from being pressed down too hard, keeping the guitar in tune and eliminating string buzzing. It's easy to use: just lock it in place with the ratchet, make minor adjustments, and you're ready to play. ■Unique ratchet arm mechanism: A ratchet (gear) system is used in the part that touches the back of the neck. Roughly align the groove (notch) that matches the thickness of the neck and lock it into place. ■ Fine adjustment screw Turn the screw on the back to adjust to the optimal pressure that eliminates buzzing, and tighten it to the minimum strength necessary for all strings to ring clearly. ■Other features: Neck back protection: Equipped with a thick cushioning pad to prevent scratches. Smart storage: When not in use, it can be secured by clipping it to the back of the nut (in front of the head). ■Imagine a capo that fits your guitar neck perfectly. The Black Mountain Guitar Capo is the world's first capo with built-in compression springs in the string pads, automatically fitting to the precise radius of your guitar neck. Once the capo is in place, these springs deform to conform to the shape of the neck, ensuring a perfect fit every time. This innovative spring-pad capo combines a ratchet system with a fine-tuning screw, allowing you to adjust string pressure as if you were pressing down on the frets with your fingers, eliminating string buzz and intonation problems. It's a truly groundbreaking advancement in capo technology! *The image is for illustrative purposes only. The instrument itself is not included.
