Play Happy at a Great Price!

The price and my curiosity overcame my doubts and I ordered a few sets of FX740 Phosopher Bronze 12's. It was a nice surprise and I quickly ordered a dozen more. They stay tuned, are easy on the fingers and fretboard, great tone and overtones when amped are bold! Even when I double capo the harmonics are right on pitch... Get some -

I have used composite 'silk & steel' strings for over 20 years on my 68 Martin Brazilian D35 12string and for 10 years on my Heritage 355 acoustic electric. I love the warm rich tones and easy fingering. Get some - Play Happy at a Great Price! When I read Martin was producing a 'flexible' core all steel string I was skeptical concerning tension and issues with capo's.

They were cheap and the flexible core idea was interesting so I bought a couple of sets. After a couple of hours playing, I can't say that I notice any big difference in playability. What I do notice is all treble, no bass. The quality is OK for the price but they are not something I would buy again.

      Comments about Martin FX740 SP Flexible Core Phosphor Bronze Light Acoustic Guitar Strings:

      I'm really liking these strings. I have used D'Adarrio exclusively for years. These strings might just top them. I admire and trust Tommy Emmanuel and these are the strings he uses and recommends. When he says they are the best sounding strings he has ever played I believe him. I have only used them a couple of days so can't vouch for longevity, but they sound absolutely fantastic. Bright and clear. Great intonation. i think I have found my new favorite strings.

        I use these on all my acoustics instead of the Tomastik-infeld's i use to use. These are just about as good and cost 1/4 the price..

          Comments about Martin FX740 SP Flexible Core Phosphor Bronze Light Acoustic Guitar Strings:

          They are great right out of the box. I gig 4 nights a week, acoustic, and I've used many strings through the years and I can put these on, FX740, and play the gig without that fresh new "piano" string sound. They last a few weeks for me. Though I know a friend who changes them every other gig. The price is great and Musician Friend's no minimum shipping charge makes them even better.

          I did a review of these strings last December. I have to update my review because these strings are the BEST I ever used by far. I have them on a Martin that I restrung last January and they still sound as good, if not better than after they first took seat.
          I only play at home these days and I change my strings at least once a month untill I tried the FX 12/54's.

            I like these strings. I don't love these strings but they sound good on my Seagull S6 and on my Orpheum resonator. I change strings every week to ten days and these set in quickly. I can change strings in the morning and play a show that evening.

              I bought these strings because my fingers are getting old and stiff. I was looking for a softer bend and smooth feel. I expected to give up some tonal qualities and volume, but, to my surprise these strings give me everything I was looking for without any sacrifice. These are great strings.

                These strings sound good. There is not a lot of string noise. However I fingerpick and they are just a little stiff for my style. I went with the 11 gauge FX775.

                    I wanted to try these a LONG time... im sorry I did, but at least I got to try.To quote the info on the Package as well as the hype...a thinner core gives greater player control increased flexibility,and improved harmonic response great flexibility ect great for transitioning from electric to acoustic and super great for beginning players. What???? I found none of this true at all! Stiff as a board I would say UNFLEXIBLE is the word. I wondered if they put the wrong strings in the box!!! Hard to play or maneuver around on! Tone sound nothing special at all..i don't get it but im very disappointed. You woud assume they would be somewhat soft similar to silk and steel and easy to play they are not.!
                    supposedly easy to bend and slide around with... nope not for me I will go back to Dadarrios custom lights they do what the Martins claim to do. I think the description was written for them by a freelance writer and it sounded good but not true... imo unplayable.. not worth it..disappointed...

                    Comments about Martin FX740 SP Flexible Core Phosphor Bronze Light Acoustic Guitar Strings:

                    Recently tried these strings on my Martin OMCA4 .
                    A relief on my fingers and my hand doesn't cramp up playing long gigs. The added plus is these Strings sound great acoustically as well as plugged into an amp.

                    Haven't experienced breakage/snapping while playing / changing strings as mentioned in a prior review.

                    I will also give the FX 80/20 lights a try on my acoustic/electric. From the reviews they also seem like a good first or second choice.
