Bravo! What a sound! It is unique. The grave is captivating, treble slammin. They are a little slippery, but I like! The price can dcourager (20 and 6 string), but they last me 3 months (instead of 3 weeks with classical strings). It's been four times longer to two times the price!! So dpensez some and enjoy! In any case do not buy in a store on the internet because they are between 12 and 16. It is even more instantly.
