Actually it's always played well and sounded good which is why I bought it in the first place. The questioning of originality would never have occurred had I not taken the neck off to check as I was changing the strings. I should probably have done it sooner, but hey, we're never too old to learn.
I've not used Rotosound strings for years however it was Billy Sheehan, I think, at the Bass Guitar Show, who commented that the majority of hit records had been made with Fender Precisions strung with Rotosound strings. I thought I'd give them a try and I'm not disappointed.
