Great Quality Strings
I’ve been using these same Martin strings on my Taylor GA4 and Mini GS for over a decade. I work on a lot of guitars. When I do setups from acoustic guitars I use these same strings unless my customer asks for something else.

Martin string comparison....
Good strings but I like the "Clapton's Choice" by Martin a little better - they're louder!!
