I recently bought a Kyser mandolin capo but I'm having a dickens of a time putting it on my mandolin (which admittedly has a slightly chunky neck profile). I was able to get it on the fretboard once but when I went to adjust it (since the treble E string course wasn't properly clamped), I couldn't get it back on. It was taking a lot of force for me to operate/open the capo and by the time I did, my hand was shaking so much that I was worried I would lose the grip on it and drop it. To be fair, I've never had a Kyser capo before (I usually use a Shubb). Does the spring get looser and the capo get easier to open/handle over time? Or should I be exchanging the capo and/or hitting the gym?
