The Nantel Verdict
The Nantel Verdict
Round core construction (unique to DR) reduces string mass while maintaining structural integrity; stainless steel windings deliver maximum brightness and sustain; 45-105 gauge balances punch with playability for standard tuning applications.
Standard 4-string set; compatible with any bass featuring standard bridge and tuning posts; no special tools required for installation; consider backup set given heavy playing wear on stainless steel construction.
Hi-Beams excel for players prioritizing cut and definition over warmth. The round core innovation delivers notable clarity advantages without compromising low-end weight, justifying the premium price point for active players.

HI-BEAM™
STAINLESS STEEL BASS STRINGS
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. HI-BEAMS are the string to choose for brightness, punch and ease of playing. Hi-Beam bass strings require much more time, care and extra steps to make than other bass strings.
- The stainless steel wrap wire produces a balanced brightness that cuts through the band
- The round core wire increases flexibility and musicality without making the tone harsh
