I use these strings on my beloved Epiphone Casino inspired by Lennon. And I've got to say they're what I was looking for. Before I mounted them I thought I would leave the G string out of the story, mounting a plain G string from another set. But then, when I saw the other strings, I just thought "I'll give it a try". So I got all the set mounted. The first thing I did was playing some old beatles song. Casino + Flatwounds is the right way. For sure, I have to say that TIs are always fantastic strings to play. I use TIs on bass and acoustic guitar too, and I've never been disappointed. I can't stop playing, it's really hard to get tired of that sound. The only negative aspect is the fact I can't bend the G string anymore. Well, I can, but matter of fact is kind of hard to reach more than a semitone. I often thought "I can't go on without bending" but THAT sound really too good. The other strings sound great as well. The B string feels quite nice even if it's a 014. A, E and D strings are quite thin, and this makes the set sound more balanced. Perfect for jazzy things, but they're good for classic 60s rock too. The only thing you would change is the G string, but I suggest to give it a try just to taste that sound. I've never tried Pyramid Gold flats, which seem really good too especially for 60s rock. But, as far as I can see, TIs JS are the perfect choice for my Epiphone Casino. Totally worth the price.
