I have a Paige capo for my acoustic guitar. When I use it the guitar has a dull sound. I’ve tried adjusting the pressure level. If I back it off a string will buzz. If I crank it more it becomes an even flatter sound. Has anyone had a similar problem and found an answer? I love the convenience of storing the capo right behind the nut so I’d love to be able to make this, or a capo like it, work.
