Like most people starting out on guitar I find 15 or 20 minutes into playing I have to stop. My fingers hurt, and I lack strength and flexibility in my ring and pinky fingers in particular. I leave this in my car and I use it similarly to a stress ball. My callouses have and I find I can now practice for an hour or more. Better than that
Like most people starting out on guitar I find 15 or 20 minutes into playing I have to stop. My fingers hurt, and I lack strength and flexibility in my ring and pinky fingers in particular. I leave this in my car and I use it similarly to a stress ball. My callouses have and I find I can now practice for an hour or more. Better than that though, my playing is much better because I have the strength to properly press the strings. Now if I can figure out how to stretch out my fingers I’ll be doing great. This is a simple gator clip with 15 lbs of tension and a bumpy surface on one side, so simple but incredibly effective.
Preparing to play again, this nifty device helps me to harden up my fingertips again! This 15-pound unit requires a bit of strength, and it prompted me to order and begin with the 8-pound FENDER callus builder first!
No problems with the unit so far, and I now use both daily. My fingers are stronger, callus formation happening, and

No problems with the unit so far, and I now use both daily. My fingers are stronger, callus formation happening, and the price was great with fast shipping! The magnet is great to store them on my metal cabinet door.
Highly recommended for new guitar players or returning back to strings!!
After 30 years, I picked up my guitars again and, of course, my finger tips were killing me. Cruising Amazon for other stuff, I came across this callus builder. Skeptical, I got it and after about a month, have developed some excellent callus to get me started. Also, I can tell my hand strength has improved. It even makes a great chip clip for your snacks. I definitely recommend it
We are the designer of the World famous finger exerciser rebranded by Fender, the World's largest guitar manufacturer
According to Andy Mooney, CEO of Fender, 90% of people that start playing a stringed instrument, stop playing within a year. WHY? The #1 reason is due to pain from lack of Calluses and Finger Strength
We designed the Perfect Pinch to simulate the strings of your instrument and help create calluses. The success of the Perfect Pinch has allowed us to sign a License agreement with Fender to bring you the Fender Callus Builder and Finger Strengthener
The Fender Callus Builder comes in two tensions, 8-lbs and and 15-lbs. No other finger exercise product provides 15-lbs of tension. And, if you move your fingers closer to the center of the Perfect Pinch, the tension increases. By just moving your fingers from the first or second raised edge to the third or fourth raised edge, you will increase the tension to over 20-lbs on the Black Fender Callus Builder. You will find it almost impossible to compress the Black Fender Callus Builder with just one finger.
Finger Exercisers, like the Fender Grip, are great for increasing finger strength and limbering up before playing. But, only the Fender Callus Builder allows you to move the product into the correct angle that your fingers will play your stringed instrument
Under normal usage, the Fender Callus Builder is warrantied for one year from the date of purchase
