Great strings, highly recommended, especially for jazz players. They are slightly pricey compared to conventional strings, but you can expect to pay more for flatwound strings anyway. These proved very nice in my hollowbody guitar, and although I am not a jazz player, I found the clarity of the sound and the lack of the usual noise from the fingers sliding on the strings imminently refreshing. I do not have a lot of experience from flatwound guitar strings, as the only other similar set I have tried in the past was a D'Addario half rounds, but these are even better. Definitely worth a try.
