Best strings for my Martin Performing Artist

These were the strings that came on the Martin GPCPA3 I got 3 years ago, and I mistakenly spent a couple years trying other strings. It finally occurred to me that maybe the original strings were actually part of the reason I selected that guitar from the many I tried, and so got a set of these. There was that sound again (sound of hand smacking forehead)! Not saying they're what will work for you, but I won't bother with any other strings from now on.

Best replacement for Taylor guitars

These have the same touch and action as the stock Elexir Nanoweb .013/.056 on Taylor guitars but have a much clearer more defined sound.Also they last much longer. I will buy some for my friends so they try them off. They will thank me for it.

I've used regular Martin SP lights on my Taylor 214 for years. I recently bought a used Taylor 510 LTD (lucky me!) and found that the SP's were a bit twangy for that guitar. After trying about half a dozen other types of strings, I switched to the Cleartone version of the SP's and I am very pleased with the tonal clarity. I play exclusively non-amplified finger style and never use a pick, so a clean, natural tone from each string is important to my ear.The lifespan of the Cleartones is fairly stunning, too. I used to change the regular SP's on my 214 every few weeks (I play a lot). Approaching the two month mark, I finally changed the Cleartones on my 510 only because I wanted to clean and oil the fret board, polish my frets, and give my instrument a little TLC. But the old set was still sounding great. So I guess the downside is that the fret board won't be serviced as often using the Cleartones.The nice thing is that the tone seems to remain constant throughout the life of the strings. After the first few hours of "spangley" newness, they settle in to a very consistent and reliable sound.

Excellent string

I've been a long-time fan of both Martin SP strings and Elixir coated strings. These Lifespan SP strings are the best of both. Clear, crisp tone and the coating doesn't shred like Elixirs do. I find that they last a good long time, too. I have them on several guitars in my collection. They have become my favorite string.

Great tone, rather short life

These strings have a great tone for the first few days. Unfortunately, they do not last longer than 20 hours of playing. Given their regular price is similar to Elixirs, I only buy them when on sale. Considering the short life and country of origin I find the full price rather high.
