I installed these D’Addario Helicore strings on my Alter Ego “Baby Ego” Figaro EUB, and I’m genuinely very happy with the result. They respond quickly, feel comfortable under the fingers, and offer a clear, focused tone that suits the instrument extremely well. The balance across the strings is even, and the overall tension feels just right for both pizzicato and arco work.
The sound is stable, clean, and controlled — exactly what I was hoping for on an electric upright. They bring out the character of the instrument without adding unwanted harshness or metallic overtones. For practice, rehearsals, and amplified situations, they perform reliably and consistently.
I can definitely see myself choosing these strings again in the future.
