Description

Allergy Advisory: Product Contains NickelAs you've probably gathered from reading our string descriptions, the selection of string can make a profound difference in response, so D'Addario offers strings in three flavors: Orchestra, Hybrid, and Pizzicato.

The Helicore Hybrid are a purposeful compromise between the extremes of their Orchestral and Pizzicato strings. While the orchestra strings are designed primarily for Arco (bowing) and the Pizzicato strings are primarily for those playing pizz (plucking), the Hybrids are made for those who happen to do a little of each! They have slightly more growl and sustain, and are not quite as bowable as the Orchestra set -- but still are quite a nice choice if you bow sometimes, but want a bit more grit and sustain than the Orchestral strings provide when playing pizz.

Includes our exclusive Gollihur Music tipsheet to get the most out of your purchaseBottom line: They make for a very good "all around" crossover sort of string for those who play in a variety of styles.

They are available in 1/2 sizes, and also come in light, medium and heavy tensions.

An Extended E/C string (for low string extensions) and a Low B string are also available in 3/4 size.

Warranty Information

I've experienced a problem with a string (or set of strings). What should I do?

We are sorry to hear of your experience. If you experience a problem with your strings (or string set), you may contact us (D'Addario) to see whether a manufacturing mishap is the cause. If you wish to return the string(s), visit http://www.daddario.com/ra. Please return the string or set in question in its original packaging (including corrosion intercept bag if possible). This will help us determine if a defect or other malfunction has occurred. Upon receipt and evaluation, if a manufacturing defect is revealed, we will quickly send you a replacement.

NOTE: Though it may not be the case in your situation, please keep in mind that premature string breakage is often caused by burrs or rough edges that develop at the nut or bridge/saddle. These rough edges are often difficult to see, but can be ruthless on strings. If your string continuously breaks at the nut or bridge, please check these points of contact for a nice, smooth surface. If burrs or rough edges are found, contact your local music shop or luthier to perform the necessary minor repair to resolve this common problem.

    Helicore Hybrids? Can't go wrong, but...

    Posted by Rafael de Sousa on Mar 2nd 2025

    As McBride is my favorite double bassist, I thought I'd give this strings a try (not to sound like him, 'cause no one can, but you know... a fan is a fan). At first, it was a mix feelings situation. It sounds too bright on my bass, but it mellows out over time. They're extremely comfortable to play, and it explains why guys like McBride and Philip Norris just fly on the fingerboard. Great, absolutely great tone. I love it! My only problem is the G string, because the gauge difference from the D is absurd - too thin. And the string texture is a bit harsh for my playing (which is a bit hard, I admit) - my fingers end up peeling after playing a 2hr-long gig, for example. Other than that, I definitely recommend these strings.

    These are the first set of strings I've put on my Bass since I purchased it new from Gollihur a little over 2 years ago. Their tone is a noticeable improvement over the stock strings. They have a nice "mwah" tone. I haven't tried them with a bow yet. That is likely my next purchase.

    Very excellent service from Gollihur Music. They quickly identified my 'unknown' upright bass string and sent out a replacement that arrived a day later. I was up and running in time for my next rehearsal. Thank you!

    This matched the set I have on my upright Kay bass and has good volume for pizz, with a crisp sound.
