Martin Acoustic Guitar Strings (41Y19MLJ13)

I put the Martin MLJ13's on my D15M and here's what I have noticed right away. The ultra-bright (in my opinion harsh) sound of new strings was absent. There is no break-in period. They bring out the rich tones of the mahogany guitar that I love. The lows, mids and highs are clear and clean, no mud. I stretched them out, about two dozen strong pulls on each string did it. They are very stable. I wait to see how long they last but right now I really like them. I do not lose any tone or volume with the 13-56 strings.

La verdad tanto como las cuerdas y las guitarras tienen una calidad impresionante las Retro Acoustic las recomiendo totalmente

Love them. Love the retro tone.

These are the strings I use on my 70 year old Martin D-18, which has massive bass and cost me $10,000. I also use them on my Martin 000-28 slot head VS, which has a very different tone and is better for finger style. These are the strings Tony Rice recommended, or close to it. I also use Monel strings on my $12,000 (used) Gibson mandolin for that old time tone, as recommended by Dave Harvey, who helped build it 21 years ago. However, he recommends .0115 for the mandolin, but I use Curt Mangan light gauge Monel strings because I prefer the warmer tone and it is already super loud. Mike Kemnitzer (Nugget mandolins—perhaps the best made) also specifies Monel strings.

a bit missing on the low end but the highs are more pronounced.
