Martin MSP4200 Phosphor SP Bronze Acoustic Guitar Strings, Medium

Very good quality strings at this price.

Rust on strings.

Avec Martin, jamais de mauvaise surprise...

da es sich um 13-er Saiten handelt, ist es klar daß man hier schon ordentlich Hornhaut braucht. Aber es lohnt sich . Der Klang ist sehr ausgewogen und ein einzelner Ton hat für sich schon eine beachtliche Intesnität. Die Saiten scheinen auch wirklich langlebig zu sein.

I purchase this one to replace my old "extra light" strings. This one sounds better and very soft in my ears. Love it

I've been playing with these strings for several years now, and I absolutely love them to death. First heard of using medium-gauge phosphor-bronze strings after looking up that Elliott Smith used them on an old, cheap Yamaha guitar. I couldn't believe it. His strings had such an incredibly bassy, warm tone to them that I assumed it had more to do with mic quality or placement, but no, amazingly, it really is just the strings.Besides the tone, the heavier gauge also allows for a few perks while playing. For one, they're so thick that you sort of have to try to knock them out of tune, and they endure the general wear-and-tear of constant playing far better than lighter-gauge strings. Secondly, as with any heavier gauge, they resonate more, and that translates into sheer volume. If you slammed your pick down on strings like these in an apartment, there is absolutely no doubt that all of your neighbors would hear you loudly and clearly. Of course, this also means that you can fingerpick without using your nails and still get a very pleasant, subdued, medium-volume tone. Honestly, light-gauge steel strings sound almost tinny to me by comparison.The biggest and perhaps only problem with these, as others have pointed out, is that, yes, they hurt. If you're new to guitar, I would really not recommend them until you at least have very solid callouses on every finger. I play guitar every day for at least an hour, and my hand still has a tendency to go slightly numb from using these. In fact, even switching guitars and playing lighter, steel strings and coming back to these makes me feel like a complete beginner, when even fretting a chord would sting until it burned. And, just like with when I was new at guitar, you get used to it, and stop noticing as much, but still: a word of caution.Overall, these are my absolute favorite strings for their warm, rich, incredibly loud tone, and their amazing longevity. If those are more important to you than anything else, string-wise, I would definitely recommend giving these a try.

Recommended for my Larivee D 03 guitar.
