Well, I'm holding in my hand "Taylor's guitar string-guide" Placed in the case when purchasing a new guitar. And it says my guitar is strung with elixir 80/20 bronze w/nanoweb.
Can't argue with your evidence!
My new GA3 (built in 2012) just has a little Elixir flyer that says "you're guitar is equipped with Elixir nanoweb strings" without mentioning what type. The only thing from Taylor on strings is how to change strings. I will try the PB when I change mine and see which I like better.
I think these "string guide folders" are kind of new. Have never seen them with my pervious Taylor's.
You should definitely try out PB next time. They are not that bright. But I think they feel a little bit harder on my fingers. But that's just me.....I think
To me elixir is the preferred string type. I have tested some Daddario's. They are quite good, but that's just the first 3 hours....
