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.
