I just replaced the stock strings that came on my new Lakland Darryl Jones 5 string. As far as I know, they were standard Lakland roundwounds, and they were really low tension. I had to lay off and play quite lightly to avoid fret buzz on the B and E strings. So, on go the Lo-Riders. I had to make a few bridge adjustments for intonation, and to set the saddle height on the B string. The original strings were a taper core B, while the Lo-Riders are not. All I can say is "wow". No more fret buzz or warbling notes on the low B. The increased tension feels so much better for my playing style and I absolutely love the feel of these strings. I've been playing Lo-Riders on all my 4 strings for a couple years now, and I can honestly say that they are the only brand of strings that will go on my new 5 string as well.
