Hi all, I just got some eurosonic steel core 'orchestra' strings, and put a G on my bass. I did not try the whole set, in hopes I can return the other 3. I'm posting this for other curious types. My opinion: not bad, not great. On my bass, it was a comfortable tension and responded well to the bow. It was darker than I expected, and not too loud. It was replacing a Flexocor Original G string. The difference I noticed immediately was that it's thinner, did not vibrate as widely, and was darker in tone. It was also less resonant on/in the bass. Pizzicato sound was thunky, but not pingy. I think the flexocor O. is better for jazz. I think these strings bow well and have a warm rich sound, but there's more pleasing strings on the market to my ear. I believe they would be more desireable if they were at a lower price point.
