D’Addario Helicore Hybrid Double Bass Strings. Stranded steel core bass string for jazz or mixed use playing styles. Daddario strings are Made in USA



D’Addario Helicore Hybrid Double Bass Strings are constructed of a multi-strand steel core that provides ease and excellent tone quality as well as superb pizzicato sustain. With the help of DAddario Musician’s Advisory Board members, D’Addario designed several Helicore double bass string varieties, including the Helicore Hybrid (HH Series). These D’Addario Helicore Hybrid Double Bass Strings are made for the bassist who plays a broad range of musical styles. All D’Addario strings are designed, engineered, and manufactured in the USA. 

Helicore Hybrid Double Bass Strings are available in three gauges, which allows for good performance across many playing styles. 

  • Light Tension: allows for easier bow response
  • Medium Tension: optimized for a majority of players
  • Heavy Tension: allows for greater projection and volume potential 

Gary’s Thoughts: Medium tension is recommended for most players, but if you are unsure which tension is for you, please contact us.


  • Perfect for a bassist who plays many styles
  • Good value for a hybrid set
  • Great pizzicato sustain
  • Responsive under the bow

    nice string set! am currently digging the sound of the helicore hybrids (medium gauge) on my Upton bass hybrid. after trying obligatos (nice tone, but the low notes on the E string just disappeared in the mix when playing with the band) and dominants (great low end and growl, but broke too often), i\’m pleasantly surprised with the helicore hybrids. pizz tone is warm and articulate, and arco is smooth. requires a bit more bow arm than obligatos and the dominants, at least for me. bonus: great price.
