Ideales para archtop y resonadoras
Recién puestas suenan muy metálicas, pero al cabo de un tiempo suenan bien y siguen sonando bien mucho tiempo. Son perfectas para archtops acústicas y para resonadoras. En guitarras acústicas tipo flat top me suenan poco cálidas.

Corde G aigue qui a pété pendant l'installation !
Le G aiguë (0.23) a pété malgré toute ma prudence et précaution. Le pire, c'est que j'ai remplacé cette corde par une d'un jeu Martin authentic tirant 10 (MA-500) Et malgré toute ma précaution redoublée, elle a aussi pété ! Finalement, j'ai remplacé la fameuse corde par une de tirant 12 et ça va. Bref, mauvaise expérience malgré le son magnifique des cordes !

Change is as good as a rest
I've bought Elixir strings for as long as I can remember and can't fault them...so why did I buy Martin strings? Well, I'd bought a Martin guitar and so thought I'd match it up with these strings as they were highly recommended. I'm not a big fan of new strings...much prefer them when they've been on a few weeks and lost that bright zingy sound. These didn't really suffer too much from that and whilst they sounded new and bright they had a rich depth from the off. I've had them on now for around 3 months and they still sound excellent and stay in tune despite some bending and changing tunings several times. They are certainly as good as Elixr strings whether they ;last as long remains to be seen but so far so good...I should add, I keep strings on for a long time as I like the dull sound as they age! I would recommend trying them as theya re a good price and I'm sure you don't need a MArtin to appreciate their sound.

Nice tone
I put a set of these on a 50 year old 12 string I had not used in a long time. These strings brought new life back into and old guitar that I was about to get rid of. Look forward to more years of use.

Produced the Vintage tone I've been chasing.
I'm not sure how these strings would sound on other guitars. But, my 2025 50s J45 Original. Sounds amazing. No fake overtones just the natural tone of the guitar. Stretched them once strung up. They break in quickly and stay in tune. This particular guitar will only wear these strings.
