## Questions & Answers

**Q: What is the difference between the Power and Super strings?**
A: Power Slinky are 2 standard gauges thicker than Super Slinky. So the only difference is the thickness of the strings.

**Q: Can these be used in drop b on a les paul style guitar**
A: I've used them drop c on my les paul and not too bad

**Q: Will these work on an acoustic guitar**
A: I always use Ernie Ball .009 -.042 on my acoustic as I like light strings and they keep a good tone for weeks.

**Q: I understand only the 4th, 5th and 6th are coated. The plain strings are the same as a normal SS pack. Is that right?**
A: Hi, These aren't coated strings. They are made of cobalt which reacts with the pickups a bit more to increase output. The 4th, 5th and 6th strings are made with cobalt but the plains are standard ernie ball plains. Thanks EmileStrings Direct
