I’ve owned this guitar for three years and my favorite strings so far have been Thomastik Infeld 11-50 Plectrums. While pricey at around $22 a set, they last 5-6 months for me. I have always found the tone very balanced in combination with great feel and good clarity as well as low string squeak/squeal. My only complaint is they are not that loud but it is not an issue for me.
Last night I put on a set of Spectrum 10-50’s (still TI) and I think they are the best strings I have ever heard on this guitar. Everything I like about the Plectrums but the clarity and volume are improved. I used the same strings recently for a 4 month trial on my Collings OM1AH with similar results. I’m trying Martin Retros one that guitar now and they are not bad but I think I like the Spectrums better. I also put the Spectrums on my K-22 12 fret but one gauge heavier due to the Koa top. The result is similar but I sure enjoy the silkier feel of the 10-50’s versus the 11-52’s.
While they are pricey, I’ve always gotten long life out of every TI string set I have tried and the combination of low tension, low noise, and good to excellent tone keeps me coming back to them. It’s kind of a relief to think my string needs may be satisfied by 1-2 string types from one brand.
