So I kept reading about how flat wounds make the Bongos all that and a bag of chips. I figured that I would try out a set on my Sterling. All I can say is "WOW", it sounds like a total different bass. Compared to my Stingray the Sterling seems a little on the bright side. The flat wounds took care of that. I would have never thought about using flat wounds on a fretted instrument. So now I'm using flat wounds on the Sterling and kept round wounds on the Stingray.
