  • Fits a Stagg EDB 3/4 perfectly!!
Size: G String Style: Medium Tension
I searched and searched for replacement strings for a friend's Stagg electric double bass (3/4) and the first two sets we tried were too short for some reason (they were 3/4 scale). The third set we tried were the standard stagg stock strings, and they were just a bit long but worked. However the G string broke during installation since we were very inexperienced with changing double bass strings. Ordered this helicore one but thought it would be too short, and to our surprise it fit perfectly! Finally got the bass up and playing after weeks of struggling to find the right strings. So I figured I'd leave a review in case anyone else ever has our same problems. Great strings! ... show more

  • Great Bass Strings
Size: Full Set Style: Medium Tension
These strings sound amazing on my ancient Bass Fiddle - I crossed over from gut & classic symphony - to these - to play in a delta blues band. They deliver well - project the sound thru the voices and still keep the beautiful deep tone from my bass (no name about 100 years old). I can keep them quite and deep - or strong and slappy!! I love them. ... show more

  • Not bad, but not the best!
Size: Full Set Style: Medium Tension
I needed some new strings and I mostly pizz, but wanted to rekindle my love for arco. The strings I normally get come from Europe , but with the tariffs there like at least $150 more so tried these. They settled in quickly like other reviews said tho are a little bright for my taste but still doing good! ... show more

  • A-OK, E, not so much, but ok now
Size: A String Style: Medium Tension
I ordered strings individually as the full set was more costly. I ordered all Hybrid medium tension, but the E string arrived as an Orchestral light tension. I have returned it and re-ordered. When I receive the correct string I will update this rating. UPDATE: I received the correct string on the 2nd order. Smooth return process. ... show more

  • I choose D'Addario strings and I haven't been disappointed. These strings are tough
Size: D String Style: Medium Tension
My youngest son plays the upright bass and when a string broke, I had to find a replacement. Lucky for me, I did my research. Based on the reviews, I choose D'Addario strings and I haven't been disappointed. These strings are tough, yet ring clear when played. And they are reasonably priced.

  • A good choice for the versatile bassist.
Size: Full Set Style: Medium Tension
These are ideal strings for the bassist who mixes a little jazz and symphonic music. The pizzicato sound is quite nice with good sustain for jazz and the arco sound is full and round. You won't get as much volume as you would with a traditional orchestral string but for those who do a little of both on one instrument this set fits the bill nicely. These strings have a fairly soft feel as well with a medium tension. ... show more
