Tried a set of these as I saw they're relatively recently introduced and my low riders needed replacing. Figure I'd try something coated to see if they last much longer, which can only be a good thing, right.
Got the "quantum" nickle 45-100 set and fitted to a sandberg california tt4. As far as im concerned this is a great match. The bass is already pretty bright and clear but these seem to have tightened up the low end further and just sound great to my ears. Maybe not to everyone's taste, of course.
They did seem to have a bit of friction against the fingers to play straight out of the packet but after playing in for an hour or so it's either gone or I no longer notice it.
If they last well, then I've probably found a string I'll stick with. For now.
Wonder if anyone else has tried them and their thoughts.
