I use these on several guitars and they are super!
Previously I have used a lot of different strings from many manufacturers, of varying thickness and in assorted materials. But these are the ones I prefer these days.
Solid tone, nice sound, heavy metallic ringing and good overtones. Just the right thickness for my playing style and fingers.
They may be a bit thick and heavy for some players, and probably not thick enough to de-tune a lot, but for western guitars in standard tuning I highly recommend them!
