## 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
