I picked up a set of them last Monday, just got around to popping them onto a bass. First thing, they didn't fit my 35" scale Roscoe, the taper on the E started before the nut, oddly enough the rest were fine, though it was a close thing with the B and A, so I'd imagine they wouldn't do for string through.
They're not really bright out of the pack, no Daddario shimmer here, but they're not bad by any stretch.
I'll see how they play over the next few days, to get a better feel for them.
