I've been playing since I was 12, and this is the first string I've been totally satisfied with. Weather I'm wailing on my old beater around the campfire or just playing my grandfather's vintage hummingbird quietly, these strings hold their tone, and produce the same great, warm, vibrant sound for months. I've yet to break one, and my friends have all switched over to masterbuilt. I can even switch to DADDAD tuning on the spot without changing strings and they don't lose tone or snap when I tune back, like all the others I have tried. Perhaps professionals may not find them bright enough, but I like the mellow tone and the vocal compatibilty. And, though its not the most important, the low price is a huge bonus.

Strings were quality packaged & vacuum sealed. I had high expectations when seeing the pride and care taken in packaging. Though the strings had a bold and confident sound they lacked the crisp, fresh voice I was expecting. Some say that these strings will make an inexpensive guitar sound great (perhaps so) but not on my Taylor. Not that they sound bad, they just did't compliment my guitar.

Amazingly Beautiful Sound

By Sam Gier

from ND

Comments about Gibson SAG-MB12 Masterbuilt Premium Phosphor Bronze Acoustic Guitar Strings:

The sound of these strings is just soo beautiful, I have been playing guitar since I was 6 and can't even count how many I'v played over the years and these are the only strings that can make your $100 guitar sound like hummingbird trust me I am not kidding, I used to use D' Addario EXP and it did not sound that good but this is simply fantastic....I will be sticking to these now... great strings at great price n if anyone of you is having a second thot mayb its coz u haven't tried this....

PURE TONE !

By Strat Lover-gwGqE

from USA

See all my reviews

Comments about Gibson SAG-MB12 Masterbuilt Premium Phosphor Bronze Acoustic Guitar Strings:

I tried about every string made on my Gibson Songwriter Rosewood and this is the string that I always came back to. I've since found that they are just as great on my Martin D-16 Sapele. Two completely different guitars and the same string is the only thing that sounds right on either one of them. The tone lasts and they don't break. I won't use anything else.

    Comments about Gibson SAG-MB12 Masterbuilt Premium Phosphor Bronze Acoustic Guitar Strings:

    I have been tried many different types and brands of strings and have finally found "the ones." These keep their tone, crispness, and clarity. Have not broken one yet. I use them on all of my guitars, which include a Guild D-55, Ovation CC44, and a Jackson/Charvel 625C. These strings bring out the best sound in each of them.

    Comments about Gibson SAG-MB12 Masterbuilt Premium Phosphor Bronze Acoustic Guitar Strings:

    I personally must have a string with a nylon wrap at the ball end for my vintage guitars. This string does not have that. For my other guitars, a less expensive string is fine.

            I have used every brand of strings under the sun in 45 years of playing. These strings came on my Gibson Dove and I wouldn't think of using anything else. I tried and hated several other brands. However, I am spoiled and change strings every 2 or 3 months regardless of wear and tear.

                Comments about Gibson SAG-MB12 Masterbuilt Premium Phosphor Bronze Acoustic Guitar Strings:

                I put these on my Blueridge Adirondack 000. They sounded awful from the start, and got worse as they broke in. I'll describe the sonic properties as sproingy, twangy, brittle, and thin. They sound like a set of Ernie Ball super slinkys, and that is no compliment. They also go out of tune very easily and seem to have major intonation problems, even when fully broken in. My guitar never had these issues until I put these strings on.

                Maybe they're better fit for Gibsons. I could not believe a set of strings could ruin the sound and feel of a guitar so effectively.

                        I use Gibson strings for all my guitars, acoustic and electric. They stay in tune well and I've never had any strings break and I've been using these strings for a little while now. I would highly recommend these strings whether you're an experienced player or not. Man I love these strings!!

                                when I switched to Gibson Masterbuilt strings, the tone of my guitars, acoustic and electric came alive. They don't break as easily, and last longer than anything I've used before. I recommend Gibson strings as the best there is.
