Savarez Classical Alliance Corum Standard/High Tension Set, .024 - .042, Plain Carbon Fiber/Corum Silver Wound, 500ARJstar rating 5Tim DonnelOctober 5, 2009Great combination of KF trebles and Hi-Tension Corum basses. No buzzing issues with trebles, but you have to be careful when tuning the high E after a string change....they can easily snap. Range and timbre of this string set is quite nice, especially for the player with no or marginal nails.
