Little over a month ago I bought a set of daddario .13-56 chrome flatwounds, I put them on my DIY archtop style acoustic which Ive modified heavily. These are the strings I needed all along, with out a doubt. Majority of the tones I've been seeking for years (apart from slide guitar) were not easily made with regular roundwound guitar strings. Never before was I able to slide so easily or create such impeccable jazz tones without these strings. I havent tried lighter gauge flatwounds yet, might put some .11 flats on my SG next string change. Been using my 'archtop' and esquire primarily for thr last couple months. I am utterly shocked that I overlooked these until just over a month ago. Im curious what you think about them.
