I've been trying to "clean up" the low B on my USA G&L L2500 for over a year now. Good sustain and huge tone, even good in the mix, but just didn't have the same clarity my other strings had. Tried DR lo-riders and Sunbeams. Tried TI Power Bass strings. Sadowsky Blue Labels with the tapered .130 solved my issue immediately. Just FYI........that tapered B works great.
