## Questions & Answers

**Q: Can these strings handle drop G?**
A: I haven't tried drop g, but I Play in drop G# no problem. I have a 26.5 scale length, so if you have a 27' it would definitely work. Probably not with a 25.5' though

**Q: would these things handle adgcfad tuning? I'm new to guitars and I wanna jam to some Korn**
A: These can take ADGCFAD perfectly fine the strings themselves are good for 25.5 inch scale length but even better on a guitar with 26.5 inch scale regardless they have clarity bite and good feel and I highly recommend them for all styles of music.

**Q: I need serious advice. Could I use the lower half of these on my 6 string, just to play music for one band? (Deftones)**
A: Yes, you can and I have as long as your bridge will fit the strings through it.  You will definitely need to adjust the setup though and the longer the scale length the better.

**Q: What is the gauge of the 3rd string supposed to be? My set came with 2 13's**
A: Gauges for the Ernie Ball 2730 set are: 10-13-17-30-42-52-62.  Thanks!
