Review: Parti' flexible.corde - Montées sur une.Martin 00018, elles ont un belle équilibre pour moi. Le son est personnel sur une guitare. Elles tiennent bien l accord mais s oxident aussi rapidement le son est profond, bon sultain Je n utilise que ces cordes maintenant. A essayer. Tout dépend de votre guitare
Review: Mis cuerdas favoritas - De momento no he cambiado desde hace mucho tiempo de modelo de cuerdas. Me encanta su sonido, y sobre todo su facilidad de tocar, notándose mas blandas al tacto que el resto, lo que facilita notablemente tocar la guitarra cuando no tienes tanta fuerza o eres aficionado. Además, de momento no he tenido ninguna rotura, las limpio siempre después de tocar y les aplico dunlop 65 de vez en cuando para lubricarlas, y ningún problema. Duran mucho, las suelo cambiar por tiempo, no por desgaste.
