I've been playing guitar professionally for over 30 years and have tried literally every brand of string I'm aware of...even some odballs that I didn't know existed until I saw them on the rack. For many years, I stuck with D-Addario Phosphor Bronze because they've been consistent with good tone and longevity. But in the Martin SP Phospher Bronze lights, I've found an even better quality string. I'm in an Irish/Celtic duo, and play a Martin OM16 in DADGAD tuning, and a 1970 Guild F30 Paul Simon in standard tuning. In both guitars, the Martin strings provide a deeper, louder tone with great sustain than any other string I've used. I recently tried a set of Elixer Nonoweb Phosphor Bronze ($16!!!!....yikes), and they didn't sound nearly as good as the Martin SPs....at less than half the price. So I immediately replaced the Elixers with SPs.

Yes, strings are a very personal item and we all have different likes and dislikes with regard to what tonal qulaities we like in our acoustic guitars. For me, I like a relatively bright, deep, sustaining tone with good volume and longevity that best brings out the chracter of my guitars, and the Martin SPs deliver big time. It's amazing how long they last after doing sessions, gigs, rehearsals, etc. The SPs last longer than any string I've used and I highly recommend them.

Prior to using these I would break strings constantly. After a very long period of trying every string out there it was an easy choice. They are the only strings I use now, and occasional efforts to find something better have failed. Super reliable, tough, and they sound fantastic on my Rainsong Jumbo. I haven't done a lot of reviews, but I truly think these are the best acoustic strings you can buy.

When I traded in my Alvarez and bought a new Martin, I stuck with my old standby string - John Pearse phosphor bronze light. And they played beautifully. When the local shop stopped carrying John Pearse, I picked up a set of D'Addario which I hadn't tried in years. And they were complete garbage - terrible sound on my Martin. Last time around I picked up some Martin SPs which again I hadn't tried in years - they sounded flat on the Alvarez. But they absolutely sing on a Martin. I didn't think anything would sound better than my old standby John Pearses. But these do. Martin SPs on a Martin - go figure, they work!

Five or six years ago, I worked at Guitar Center. Getting strings at cost allowed me to experiment with pretty much every make and model of strings available. I found a lot of close matches, but had a hard time finding what I was looking for. I decided to give these relatively inexpensive Martin SP's a try and they really fit the bill. I tried both the 80/20 and the 92/8 phosphor bronze. The 80/20's sounded thin and tinny in comparison, but it will depend on the tonal qualities of your guitar. Both are excellent strings, but I prefer the 92/8 on my Seagul.

Pros:

Very deep sounding bass and midrange. The wound strings really stand out and have a nice pop to them.

The high strings aren't abrasive (tonally). The set as a whole is very balanced and easy on the ears.

Impressively long life for an uncoated string. Granted, I use these in a dry, studio setting, but I can make a single set of strings last between one and two months, playing extensively almost every single day. I'd say I get between 100 and 150 hours of playing time out of these (always wash your hands before you play guitar!).

I have NEVER broken a string (imagine that). I'm probably about average when it comes to the beating I give my strings. I can't speak for the all too prevalent heavy handed picker.

They're inexpensive! Not only are they 1/3 the price of a set of Elixirs, but they sound better, last longer, and they don't start flaking and pealing after a week.

Cons:

They are quite bright and tend to rattle a bit for the first couple hours of break in time. They mellow out rather quickly, however.

As a fellow reviewer noted, they do, indeed, turn your fingertips black.

I have been playing guitar for fifteen years and in the last two or three of those years I've played strictly acoustic guitar. I've tried just about every string out on the market today and different gauges too.. Coated, non coated, nickel, phosphor, etc.. First of all I don't like the coated strings, for people who say elixirs are the greatest thing since sliced bread, I would say they are tone deaf.. And yes I have also tried the "Cryogenically frozen" blue steels from Dean Markley. While Dean Markley does make some strings that would be in my top 5 list, the blue steels sound too jangley. People have told me, "try the D'addiario phosphor bronze," they sound too bright! After all of that experimenting I thought, well I play a Martin SWOMGT so why not give Martin strings a try? and after a couple of gauge changes I found the Martin SP Phosphor bronze light strings and It changed my guitar playing forever. These strings are hands down the BEST strings you can buy for the very reasonable price PERIOD.. Their not bright, their not too dark or jangley. They produce a beautiful not too clear but just right tone and sound. To make a long story short I've never wrote a review on Amazon before but I found these strings to be so helpful to me that I had to share and hopefully spread the joy!
