Hi-Beam stainless steel bass strings are round wound and constructed on a round core which is unique in the industry. Hi-Beams require much more time, care and extra steps to make than other bass strings. The extra effort DR expends making Hi-Beams results in a bass string that is highly flexible and musically but not harshly bright. They are renowned for durability, unusually long life, consistency and string-to-string balance. They don’t eat your frets.
