Review: Melhor produto da linha com o melhor custo-benefício.
Review: Ich habe diese Saiten auf meiner IBANEZ RGA32 gespielt und war von Anfang an begeistert. Warum? Saitengefühl - Sound - Stimmstabilität - Korrosionsresistenz. Ich habe den Satz seit nun 7 Monaten auf meiner IBANEZ und keinerlei spuren von Oxidation auf den Saiten. Ich empfehle sie gerne und ohne Gedanken weiter.

## Questions & Answers

**Q: Are these made from cobalt mined by dwarves in the mines of Moria? Someone on the internets said so.**
A: Now we know why ErnieBall cobalt strings make most magical sound vibrations 🎶mines of Moria, dwarves & elvin magic ✨

**Q: Are they better for finger-picking?**
A: I installed these strings on a 72 fender telecaster thinline with wide range pickups using a fender supersonic 60 watt tube amp and found the sound difference from the Ernie ball super slinky strings I usually use to be harsh. There was more treble then I wanted and an almost chimey sound from the higher notes. This is not a string suited for country music which is what I was playing. It accents the finger picking well by making each individual note stand out more clearly but the louder I played it started distorting and under distortion it was an unpleasant sound. Best stick to the tried and true Ernie ball slinky and super slinky for finger picking. In fact on my american start with single coils the slinky strings sound the best by far for country music. Tuffet to bend then super slinky but a much more rounded tonal quality then these cobalt strings. I hope this review helps.

**Q: are these strings round wound or flat wound?**
A: Strings are round wound.

**Q: Are the 3-packs individually wrapped packages that can be sold separately? Or is it 3 sets of strings in one package?**
A: The 3-packs come in one package, but you can separate them once you open up the package.If this was helpful, please consider purchasing from us. We can help with support after the sale as well. We have it in stock and ready to ship. - Pixel Pro Audio

### ⭐⭐⭐⭐⭐ Review
*by M***R on 14 May 2024*

I used original Slinky strings for the last 20 years and I decided to try the newer cobalt version and I am really impressed by them. The sound output is louder and it is warmer than the original's. The sound quality does not drop as fast as the original's so they effectively last longer. String tension is a tad higher than the original. So you should have your guitar setup redone as it's going to mess with your neck relief and intonation. I ran into problems with 2 .009 stings (which broke instantly) and Ernie Balls were quick to help me and replace them free of charge. Great service!!! I am happy with these stings and I don't plan to go back to the originals.
