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.

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.

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.

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.

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.

Amazon is the only place I could find these strings

I couldn’t find these at Guitar Center, but I found them here, and they play/sound great. Like many of the other reviewers, I have a Martin D-15M. Medium gauge strings sound incredible of course, but they are hard on the fingers. Light gauge strings sounded too thin. These ones truly are the “Goldilocks” strings. I also threw a set of these on my older Martin DM guitar and they play/sound great on that one too.

I have always liked the strings and now own 5 Martin guitars

Martin SP strings were supplied with my new Martin 000-28VS purchased in 1999. I have always liked the strings and now own 5 Martin guitars. The brass plating on the plain strings helps keep them going since I don’t change them very often.

I strung that bad boy with these strings and haven’t looked back

My wife got me a JB Player 409 for Christmas at a used instrument/pawn shop type of place. I strung that bad boy with these strings and haven’t looked back. Such great sustain and volume. I can do a 10 fret slide and it sounds killer. Pull offs and hammer ons are the sh*t with these strings. I love them! Edit: They stay in tune great. I can capo to play in A and take the capo off to go back to G and it’s still in perfect tune.

Perfect….for me

I’ve been unhappy with most string sets for years. I like light strings for picking and trying to play anything particularly fast but they get pulled out of tune very quickly if you’re as much of a ham-fisted doofus as I am. Light sets are also just too quiet if you are a loud singer like my self. I like heavies because they project so much more and stay in tune for much longer, even if you grip your guitar neck like a steering wheel during a car wreck, but they can be exhausting on your fingertips and not particularly responsive to light picking, bending and anything subtle. This Martin Light-Medium set is really the best of both worlds and I highly recommend them if you’re like me and sing too loud, play too hard, have hands of concrete and pull everything out of tune, while demanding light response and reaction for the odd times you try something subtle and tasteful.

but put these Martin strings on my new acoustic and it sounds better than *ANYTHING* I’ve ever played before

I may never buy another brand again. I’ve used Elixir and D’Addario for years, but put these Martin strings on my new acoustic and it sounds better than *ANYTHING* I’ve ever played before, including my electrics.

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.
