After 15 years of playing, these ones stole my heart and fingers. Those guitarists, who struggle to play faster and to sound more precise and brighter - here is the solution. Supreme control, smooth feeling, great attack, and the Root's logos on the pick gives surprisingly great grip. These could be suitable not only for stringbreaking attack upon riffage, and sniper shreddy licks and solos, but for every genre when you want to sound brighter. Durability is an understatement. The edges are very resistant to grind down even with a harsh playing style.
First I thought that it would be hard to shift from my old friends 0.96 Dunlops, but when I first touch and play with 1.38 Tortex-Jazzes send all old packs to thrash. You just don't want to play with others anymore.
Pros, pros and pros, No cons.
For those who find perfect control and punchy sound, you should also try John Petrucci Jazz III. They are comparably smaller and thicker, but also sound perfect. Personally, I use both types for last years, JR for everything and JP for the fastest picking and for the punchiest riffs. Beardy Johns know something about how to sound outstanding =)
