These strings are produced with a solid core of steel. Therefore they are strong and powerful in tone and give to the musician a brilliant sound and a confident mastery of his instrument when playing. The Precision steel strings are not a new concept, just the opposite - their production is based on the oldest ideology of Dr. Thomastik. Since 1920, they have been manufactured to the same high quality making them ideal for student musicians and for folklore music. The precision string is very popular as a result of its favourable price and long duration of life.
