Like all the Martin SP Studio/Performance Series strings, the MSP4150 SP Phosphor Bronze Light/Medium acoustic guitar strings are ideal live, in the studio, or wherever maximum string life is desired. The creation of these high-performance Martin strings is a result of research done in cooperation with specialty steel producers. Due to the development of a top-notch ultra-high quality steel core, Martin SP strings resist breakage better than average strings. In addition, both the core wires and the plain strings are plated with a smooth, acoustic bronze finish. Though this golden bronze finish will enhance the beauty of your guitar, its purpose is much more functional—to prolong brightness, guitar string life, and provide superior tonal quality to meet the high expectations of demanding musicians.

A Nice Sounding Set of Strings.

A great set of strings, though wouldn’t recommend these for the beginner who hasn’t built up their calluses yet. (would recommend the lights for that). The sound of these strings are GREAT on my Appalachian. (A $100 knock off of a martin acoustic, with a very similar sound to the original martin, to boot. ) The only major draw back to these strings is that they will cut into your fingers if your a beginner or haven’t played in a while, but I do think the sound quality does adequately compensate for this.

Great Acoustic Strings

Didn’t know whether I would like these strings or not. Well, they passed the test. I haven’t played in years and the strings were a nice weight even for my fingers. They had a great sound and made my old acoustic guitar sound more professional. Love these strings.

Nice sounding and fairly loud.

I like to play an ovation 1111 from the 60’s. I always used martin medium bronze with great results. The old guitar really broadcasts well. Recently the head decided to snap. I noticed the problem when I opened the case after the grandkids borrowed it. Of course everyone was dumbfound as to how it happened. It was one of those after 50 years I loan it out and it breaks itself in a week. So much for complaining. I glued it back as good as new and put these strings on because I am worried of the tension. I probably shouldn’t be because the glues are very strong. Stronger than the wood. Well it has now been a week of pretty hard playing and the guitar sound as good as ever. These strings are just fine. They don’t have the depth of the medium big brothers but they sound great for folk and bluegrass work. I may just switch. The Amazon price is right.

Great guitar strings! If you’re looking for good quality acoustic guitar strings then look no further because you’re looking at them! Very light and the sound quality is just like those guitar strings they use in recording studios, Truly remarkable product. I highly recommend this strings because Martin Guitars (The Makers of this strings) is a good company and they make one of the very best guitars you can buy.

Love the tone, volume and playability.

I’ve been playing guitar for over 45 years going through so many acoustic strings. I just happened to be most comfortable and confident with Martin strings. These particular strings however I’ve found the ultimate balance in tone, volume and playability. Can play for hours with these strings in any setting.

Warm tone that pairs nicely with a naturally brighter guitar

I’ve played with D’Addario EJ16s for a long time, but recently I decided to try out something different. So far, the MSP4150s have been great match for my Yamaha FG730s. The combination of the warm tone of the strings with the brightness of the guitar gives it a very lively, dynamic sound. While the EJ16s are still great and I wouldn’t flinch if I went to change my strings and that’s all I had available, I think the MSP4150s will be my preferred choice going forward.

Not for me on my Martin Jr.

Don’t know why but these feel stiff and the treble doesn’t sparkle like the D’Addario PB EXP I had in before (Bluegrass).They’re not that different in gauge than the ones I had in before.Just a personal preference but I’m going back.

Reasonable compromise between tone and playability

 on September 1, 2017
By osguthjd
These strings represent a reasonable compromise for my dreadnought sized guitar between the fuller sound of medium strings and the playability (for longer sessions) of lights strings, without as much of the tinny voice associated with the latter. For my parlor sized guitar (OOO), light weight strings are fine, and indeed the manufacturer (Martin) specifies such.

On my acoustic, I have always gone with medium/heavy strings because of the deep, high quality sound. But they are a bit hard on the fingers and don’t stretch as easily as I would like. I decided to try these Martin light/medium this time around, and quite glad I did. They provide a rich enough tone, and make guitar playing a very enjoyable experience, as it should be. Also great quality at a very fair price. Probably will stick with this brand from now on.

Best strings around…

Martin SP is my top favorite string. I would wait to change them if I could not find the right strings. As a fingerstyle player, they sound just how I want them to.

Martin Acoustic SP Strings/SWOMGT Review

Hey guys! Today I'm reviewing Martin Acoustic SP strings as well as the Martin SWOMGT guitar. I set up a Audio-Technica 2035 mic to record the pure sound of the guitar.

The strings are light gauged (.012-.054) MSP4100 phosphor bronze.

The guitar is the SWOMGT (Sustainable Wood OM Gloss Top).

I love both, and I hope this video can help you get a listen of both and can help you get an idea of them and their qualities.
