There's allot of sharp picks in the world, but with Dunlops jazz 3 series it's a totally different thing. The tip is sharp, but also a bit round, so it's easy to push it trough the string, unlike others. The roundness prevents the tip from getting caught in the strings. Also the roundness prevents the pick from wearing out premature.
You can easily play 10 and more gigs with the one pick and have no worries.
i recommend everybody to get these pick just for a test. A real Metalheads tool.
The jazz 3 is great with guitar and 'cause of its small size it's the best for accurate picking. The jazz 3XL is great for not only guitar, but for bass also. Buy it, try it, love it!
