I just restrung my Yamaha 5er with a set of Labella super steps (128-045 gauge) and all I can say is wow. What a great set of strings. I haven't been this happy with my tone in almost a year. This is on a budget bass through my 30watt practice amp. Granted the set of strings I had on before were over two years old.... Anyway, I don't know if it's the strings or the exposed cores but I find the B string to be really crystal clear and resonant. As opposed to a rumble with a hint of a B note but an octave up. What a great set. And cheaper than the DRs I used to get too!
