Review: Solid strings with a balanced sound - Excellent tone and feel These strings sound great right out of the package and feel comfortable under the fingers. The medium-light gauge is a good balance of warmth and playability, and they tuned up quickly without much stretching. I’ve been playing acoustic guitar for years and these delivered exactly what I expected—clear tone, consistent quality, and solid feel across all strings. I’d happily buy these again.
Review: Quality at Value Price - I strung these on a Parlor guitar - I really like the sound they give the small bodied guitar. Sounds rich and full. Also easy to play. I think the longevity is also really strong. I have had them on a long time and I feel they sound equal or better than when I just put them on. I am just a casual player - but I really think these are quality at a value price.

## Questions & Answers

**Q: What would be the downside of putting these strings on an old classical guitar I bought for $25. Would it cause the neck to bow?**
A: Your guitar will be damaged on a classical with steel strings. Classical guitars necks are not built for steel they are built for nylon strings. Your neck will bow and warp

**Q: Are the first 3 strings nylon?**
A: No, they are plain steel as in other acoustic sets. Nylon would only be found on classical sets.

**Q: What would be the best string size to use on a used acoustic guitar to be played by a 9 year old boy?**
A: The lighter the guage...the easier to bend.
The easier to bend...the harder to control.
Since its an acoustic guitar, i would start with 10's ...try .10 to .46. Thats a pretty standard guage. 
He should be able to tell if he would like a smaller guage in which case go to 9's. 
Better yet....take him to a guitar shop and let him try some different guage strings. 
If hes just strumming, he may like the 10's.  When hes ready for more sophisticated play, and until his hands get larger and stronger,  he may need the 9's.  Happy playing!

**Q: Can I put nylon strings on a guitar that use to have metal?**
A: You can. You will need to do a neck adjustment to makeup for the lower tension. These strings are metal that the question was asked under.

### ⭐⭐⭐⭐⭐ Warm, Balanced Tone and Reliable Quality
*by K***P on December 22, 2025*

Ernie Ball Earthwood acoustic strings are a solid choice if you want a warm, balanced tone without sacrificing clarity. Right out of the package, they sound bright but not harsh, and they settle into a really nice, full sound after a short break-in period. The medium light gauge (12–54) feels comfortable under the fingers while still offering good volume and projection. They’re easy to install and hold tuning well, even after several playing sessions. I mainly use them for casual playing and longer practice sessions, and they stay consistent without going dead too quickly. They also feel smooth enough for strumming and fingerpicking without feeling stiff. Overall, these are dependable, great-sounding strings at a reasonable price. A good option for players who want quality acoustic tone without overthinking it.
