Designed in the shape of Fender's world-famous Stratocaster Guitar. Raised Ridges – The only finger exerciser with ridges that simulate the strings of a stringed instrument. Helps build finger ringing - A callus is a thickened area of skin that responds to repeated friction, pressure, or other stimuli. The Fender Callus Builder is designed to create pressure similar to the strings of a stringed instrument. Simulate Precise Angles – Easily interact with Fender Callus Builder to use precise angles while playing stringed instruments. HIGH TENSION - Two different resistance levels, red, 8 lbs and black 15 lbs. The 15 pound tension is extremely stiff and provides more tension than other finger exercisers on the market. To play a stringed instrument, it is essential to make an octopus.More than 2 million new people start playing stringed instruments every year. After 12 months, 90% will stop playing. The main reason for quitting is pain due to calluses and lack of finger strength. The Fender Calus Builder and Finger Strengthener was designed to help in both of these areas. Easily recreate the exact angle at which you play your instrument. Unlike most finger exercisers, the Fender Calus Builder can be held at different angles, allowing the user to exercise at the same angle as they play their instrument. Which strength is right for you? The Fender Calus Builder is available in two tensions: Red = 8 lbs. and Black = 15 lbs. These tensions were measured with a force meter applied between the first and second outer projections. Moving your finger closer to the center will increase the tension. For example, if you apply pressure between the third and fourth protrusions, the tension will increase by 50%. Provides 15 pounds of tension We don't know of any other finger exerciser that can increase tension to more than 20 pounds by simply moving the fingers closer to the center. For beginners, a perfect pinch of red is sufficient. As you strengthen and improve, you'll need the perfect pinch of black. If you are an experienced musician or bass player, you may want to use the black Fender Calus Builder. We offer combo packages at discounted prices.
