I love these strings. I use them on my 5-string modified Fender Jazz Bass (with Sadowsky pre-amp). I use the heavy gauge because on fenders the B string is typically quite floppy. But with the added thickness of the heavy gauge, the B string is snug and tight, and the sound is tight too. If you manage to keep a light touch, it sounds just as even as the other strings, and if you dig in, you get a nice gnarly tone. I've had them on for over a year, and there's absolutely no corrosion on them, and sound is still nice and bright.
