What is your overall opinion of this product?
I have used Rotosound strings on all my basses for many decades. I've tried other brands, and some sound pretty good but I always come back to these.
They are kind of tough on your frets. Also, they begin life as a pretty bright string, but usually die down to a point where I change them every couple to three months. Keeping them clean I've found is key. If you like strings with a great Rock tone, that have a little growl and snot to them, these will do it for you.
