I don't think it's that simple, or at least it isn't for me.

There are lots of guitars with lots of different sounds, so ostensibly we've all purchased guitars that sound exactly the way we'd like. Maybe, but probably not. Lot's of decisions go into the purchase process. I suppose if you like the sound of the guitar a good place to start is with a string that reinforces that tone.

Then we get to our own ears, or what we'd like to hear from strings. On players dark and lush is another players idea of dull. Add to that mix the kind of music you play, if you use a pick and if you need to cut through an ensemble. Lot's of possibilities.

I don't think there is a better way than investing in a big pile of strings and seeing what works. As an example: D'Addario are popular strings and for me they just don't get the job done. I play with bare fingers and want to hear more guitar and less string. That's good for me, but clearly not necessarily for you.

Currently my favorites are Martin Retro's on the 000 and SUS on the Lowden.
