The Mari family was among the earliest string makers in 17th century Italy. They began with gut strings for violins, and relocated to New York City in 1913, adding steel strings to their popular line. Currently in Newburgh, New York, they are one of the largest and most well-respected manufacturers of strings for a variety of instruments. In their Hard Rockin' Steel (HRS) strings, they use nickel-plated hand wound technology, using fine nickel wire from American wire mills. The use of hard temper wire makes them resistant to string wear, adding to their durability and longevity. La Bella Hard Rockin' Steel strings are available in different gauge sets for individual instrument characteristics and to complement various playing styles. The Light set has gauges between .009 and .046. La Bella Hard Rockin' HRS-M Medium gauge strings are .010 to .048. These hard rockin' steel medium strings may be the best set to try first, as they offer a good range for a rich, bright tone.
