Bought these yesterday because I wanted a flat that was more traditional in flavor and was available at my local shop. I bought the Group III .45-.100 and right out of the package I thought they were Chromes. They look like they are wound the same and even have a similar blue silk. I was sort of bummed. I was put off enough to put them on my Warwick Corvette instead of my Ibanez Blazer (a Pbass clone) because I thought they would sound much like Chromes which don't have a classic flatwound tone to my ears. The Corvette has had Chromes on it before and their ringing/brighter tone sounded cool on it. Got the Ernie Balls on and they really are nothing like the Chromes except in looks. They are smoother and far less bright and twangy. Smooth and buttery with a nice and even decay. Musical and not just outright dead thump(which will be fun to see if they get to that dead thump sound at some point in the future). I also liked the fact that they are less tense under my fingers than the Chromes of the same gauge. They seem like they will mellow nicely into an even more vintage tone with time. I will be switching them to the Blazer now that I have found them to be what I was looking for. I let the looks fool me into thinking I had bought a Chrome's clone but these have turned into a fun surprise!
