Over the past few years, I've been a user of Ernie Ball Slinky Cobalt flats. I love the sound of these strings, and it's hard to find flatwounds that are wound with something other than stainless steel, which I don't care for. But I will use them no more. It's bad enough that they raised their price 25% a few months back, as was noted in another post, but now they're making shoddy strings. I bought two sets of them a while back, and recently bought a new bass, so I put a set on this bass. I intonated the bass, and the G-string played in tune only when open and on the 12th fret. It was radically sharp on fret one, gradually getting closer to pitch until, at fret 12, it was on. Above fret 12, it went flat. I took it to my luthier, who ran a series of checks on it and told me it was the string. I put the G-string from another new set of the EBs on it, and this one couldn't even be intonated. I took the G-string off my Jazz Bass. It is also an Ernie Ball Slinky Cobalt flat, but an older one. It's fine on either bass. So I got two bad G-strings from two new sets in a row of Ernie Ball Slinky Cobalt flats. One set I bought about a month ago through Amazon and the other one six months ago from Sweetwater. I don't know if anyone else has had issues with these, but I recommend avoiding them if possible.
