Hi Beams 4 String Bass Extra Lite 30 90

DR Strings Hi-Beams stainless steel bass strings are round wound and constructed upon 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, musically bright (not harshly bright) and renowned for durability, unusually long life, consistency and string-to-string balance. They also don't eat your frets.
