DR Strings Hi-Beams Heavy 4-String Bass Strings.

Gauges 50-70-90-110. Hi-Beam Stainless Steel Bass Strings are roundwound 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 results in a bass string that is highly flexible and musically bright without harshness. Hi-Beams are renowned for unusually long life, consistency, and string-to-string balance. They don't eat your frets. Choose them for brightness and ease of playing. They fit virtually all scale lengths up to 37-3/4".
