I have used many types of capo over the years and the whole topic about which type is best is subjective from one musician to the next.
I have laid off sprung capos for well over 20 years until I saw this design and,as I have had a few tuning issues with other makes I thought I'd have a look at this.
It is superb,well made, well finished, and quick to use.
Tuning is good and the capo sits out of the way on top of the headstock.
Great product that I can recommend.
