Different Strokes

By SportyGringo

Choosing strings for your acoustic is quite a task. Before you know what you like you have to try a wide variety because different guitars sound better with different strings. I have a few guitars and I use many different kinds of strings on all of them, but with my Seagull Artist series I use these and the tone is to die for. The lows are loud and clear and the highs shout out for all to hear. They even sound great plugged in. So if you have the money, try a pair of these out, they are my favorite Martins.


Rat Tail File Strings

By Charlie Powell

from Fort Worth, Texas

I tried the Elixer Nanoweb medium strings which sounded good but a bit mellow but had very good playability, so I decided to try Martin 4200 Phosphor Bronze Coated strings for comparison. Immediately, the Martin wound strings felt like I was sliding my fingers on a rat tail file. Sliding on the strings produced a significant scratching sound which is the product of the rough finish of the coated Martin strings. The playability was poor and unacceptable. The sound of the strings was a bit brighter than the Elixers, but that could be because they are new. I'm disappointed.


very good and long lasting

a very good string long lasting with very little re-tuning needed


Coating Not Needed

By Anonymous

from Undisclosed

These strings say "Extended Life" but the special coating adds almost nothing to the long life and tone you get out of the standard Martin SPs. The strings are GREAT, don't get me wrong, but whatever upside the coated version has it isn't worth the extra $ per pack. Do yourself a favor, save the money and stick with the regular SPs.


Awesome Strings

By Kerbinator

from Emporia, KS

I bought these to replace the factory strings on my brand new Washburn D100 and the difference is PHENOMENAL. I had no idea my cheap guitar could sound this great. They are pretty expensive, but if they last as long as they claim, I'd say they're worth it.


Good but they don't hold a candle to elixirs.

I bought 2 sets of these expecting the great quality of Martin and the lifespan of polywebs or at least nanowebs. I would recomend these strings. I gave the second set away and just ordered some elixir polywebs.


great strings

I have been playing for over 40 years and started using black diamond steel at a buck fifty a set, since then I?ve used a lot of different strings on a lot of different guitars. I find that these are the longest lasting strings and best sounding on my HD 28 That I have ever used.


Died too soon

By Jerms

I swear by the regular Martin Phosphor Bronze SP mediums for my D-28 which I play in my bluegrass band, and thought maybe I could get 2 or 3 gigs out of a set of these, but halfway through the second gig they died, and sounded more dead than any strings I've ever had on that guitar. They sounded dull and plunky like my guitar had been strung with a dead cat or something. Plus they sounded worn in as soon as I put them on, like they'd been put through the paces already. I normally like the way the regular msp4200s sound when they're broken in after several hours' playing, but these sounded almost worn out when I put them on. Plus they corroded just as must as the un-coated version does. In my opinion, paying double for a set of otherwise perfect guitar strings with a coating that just deadens their sound doesn't make sense.
