I simply love the capos that have the tension screw, much easier to handle and you can adjust the tension on the strings. I still have my old capo with spring but I use it only for acoustic - it has too much tension for the electric guitar and 0.010 strings.
But the simple and effective design of the Daddario capo works great. It seems solid and it should last a lifetime.
The radius of this capo works with all of my acoustic and electric guitars, Les pauls, strats and tele types.
Sure, it takes some time to fine tune the grip and the position - but once you manage its easy. Simply the best capo to get the job done. I have manage to adjust the tuning with tuners with the capo fitted on the neck, but you must make sure it is not too tight before trying to do that.
I have nothing bad to say about this product, it seems almost perfect. It would be cool if they would produce it in other colours too - blue, green, yellow, white or any other color would make things a little more fun.
Highly recommended for hobby and profesional use, reliable, well built, affordable and easy to use.
