Ernie Ball String Explorer: Acoustic Earthwood Phosphor Bronze - C.F. Martin D-28

Ernie Ball: String Alloys - Acoustic Earthwood Phosphor Bronze

Description
Ernie Ball launched their 2151 Earthwood Phosphor Bronze Rock and Blues Acoustic Guitar Strings, and they are flying off the shelves and into the hands of guitarists who want that classic Ernie Ball sound and guitar strings that are built to last. Ernie Ball has long dominated the music marketplace for quality instrument strings because of their professional-grade sound and reliable tone capabilities. All players feel proud when their guitar, bass, mandolin, banjo, or lap-steel is suited-up with Ernie Ball strings and guitar accessories. These phosphor bronze rock and blues strings have an added grit that truly beefs up your tone and projection.
A Successful Combination of Quality Materials
Phosphor Bronze is a member of the family of copper alloys. It combines phosphor and tin, and occasionally additional materials. In this case, they are constructed with 92% copper, 7.7% tin, and 0.3% phosphorus wire wound upon a hex-shaped, tin-plated steel core wire. These strings produce an edgy and articulate punch with full-bodied overtones that guitarists love. Their gauge range is .010-.052.
Greatness Takes Time to Procure
Back in the day, Ernie Ball tried to persuade many large guitar manufacturers to create a line of thinner guitar strings because he foresaw the tone range potential, but no company realized the true need for newly designed and innovative instrument strings. Since establishing his own successful string line, Ernie Ball strings have been showcased in hundreds of top-selling albums across all musical genres and have decorated the guitars of some the most famous musicians on the planet including The Rolling Stones, Angus Young, Eric Clapton, Jeff Beck, Jimmy Page, Paul McCartney, Pete Townshed, Aerosmith, Metallica, just to name a few.

A must try for acoustic lead players
These strings are incredible for the acoustic leads @ duo or full group gigs. Even rhythm players will enjoy the "comfort" of the plain 'G' string in this set. If you've never played with a plain G on an acoustic, you will have to adjust your usage. If you've been using "Ray Flacke" fingers and manhandling the G string, you will have to adjust. Once you do, you'll never want anything different on your guitar. Sound and depth of sound is not an issue. They also sound excellent in the studio.

Will not buy again
Recommended by an associate I got these to replace on an SC13e that had been on the wall several months. Upon installation, I realized they are too light. The neck on the guitar required a truss rod adjustment by a GC Tech. The strings were fretting out. I have restrung 4 other SC guitars with either 12/53 or 11.5/47's. No issues. The B and Hi E strings "plink" too much even after the rod adjustment. I do love their playability and how they bend easily. I may try the same brand in a heavier gauge.

I've bought these strings before and they were amazing, snapped the A string while adding them and had to use the old one (my fault, first time replacing strings), but they've reliable even though I've grown out of the 7th chords now and adopt new styles.
Love them

Will the lighter gauge strings(especially the plain G) affect the action or cause fret-buzz or twang?
The lighter gauge is going to affect the neck. The action shouldn't be affected but there will be less tension and it will be theoretically easier to fret. It may cause some buzzing, it may not. the only way to know is to try. You may want to have a tech look at it, just for advice.
