Review: j'ai pas un haut niveau, je joue depuis 2ans, et au debut j'utilisai les cordes de la marque Ibanez, mais elles cassaient régulièrement (1/mois), puis je trouvais le son brouillon... J'ai testé celle-ci voulant un son plus cristallin (même dans l'énervé !) et je suis tombé sur le cul... Le son est précis, ça respond au poil , et ça tient ! j'attend de voir mais déjà 3mois sans soucis à bender et à attaquer :) Le must pour ma part
