Description This capo suits steel string Acoustic guitars. Since 1980 the Shubb capo has set the standard against which all others must be measured. It is the first choice … often the only choice… of more than a million musicians worldwide. The serious guitarist will settle for no less. What makes the Shubb capo so special? For one thing, its ingenious design: a patented locking action which provides an unrivalled combination of power, speed, accuracy and ease of use. One smooth flip of the lever locks it securely in place… and removes it just as quickly. And the Shubb capo doesn’t create tuning problems. Its soft, resilient rubber is specially designed to work just like a fingertip, so it doesn’t bend the strings over the frets. Its closing action is just like your hand, so it doesn’t pull the string off center. As a result, no re-tuning is necessary! Precisely machined  and carefully hand assembled, a Shubb capo is manufactured without compromise. Simply holding one in your hand conveys a sense of quality. Snapping it solidly onto a guitar neck, and then removing it, all within about one second, will confirm its reputation for excellence. When developing this capo, the main job was to minimize or eliminate the need for retuning. This was accomplished by designing a unique material that acts just like your fingertip a patented closing action that works exactly like your hand. Most capos use a material to press the strings that is too hard. It bends the string over the fret, stretching it sharp. The thicker the string, especially wound strings, the more drastic the effect. We worked with a laboratory to scientifically formulate a special, custom rubber material that behaves just like the flesh of your fingertip. It allows the string to sink into the rubber just enough for it to relax, and not get stretched across the fret. Meanwhile, the metal rod inside acts like the bone in your finger to back up the resilient rubber. Result: the strings are NOT STRETCHED OUT OF TUNE!
