Questions
What tuning is .5: The Gray Chapter in?
Slipknot recorded .5: The Gray Chapter (2014) in Drop B at concert pitch (A 440), measured by TuneLit on the CD. XIX uses Drop B +39 ¢; Sarcastrophe and The Devil in I use Drop A.
Why does .5: The Gray Chapter sound out of tune with my guitar?
XIX sits about 39 cents sharp (A ≈ 450), so a guitar tuned to A 440 clashes with it. The Tune buttons on this page set the tuner's reference to match the record, so you only tune the strings.
