The capo is a fantastic invention and these little wonders can bring wonderful benefits to guitar playing. There are a wide variety of capos on the market each with their own benefits but also their quirks too. The Ernie Ball Axis capo helps solve a few of these. Firstly, it’s rare to see a capo that will fit both 6-string and 7-string width fretboards. In the past, you will have had to buy separate capos for different guitars. Possibly the most unique feature of the Axis capo is their ‘dual radius’ design which shapes nicely to the radius of your fingerboard ensuring even pressure distribution is applied across all your strings.
