I currently use these strings on a cheap Baton Rouge 12-string. The usual Bronze strings usually sound a little too harsh on this guitar.
The GHS 610, though, sound sparkly, brilliant and yet have a mellow quality to them, although they are light on the very bottom end of the frequency spectrum – if that's con for you depends on your specific preferences, I'd say.
Playability is amazing. I can wholeheartedly recommend these strings. Just be aware that they are indeed coated in silver, so they will lose their shiny finish after a short period.
