Rotosound BBL030 Phosphor Bronze Roundwound single High C string, .030

Won't use anything else.

There aren't too many reasonably priced options for high C strings for an acoustic bass so I'm glad I found this Rotosound string. It's is my go-to for price and sound. Like all strings, it loses that out-of-the-bag brightness before too long... but that's not a knock on the product quality. In my experience, that's just the way all guitar strings seem to be, irrespective of price point. I definitely recommend this string.
