So yes, today I decided to learn to play a song from Helloween called "Escalation 666". I tried to search through the Internet and I can't find any info about the notes nor the tuning. So, in order to help others, I tried myself to do a tab of it. But I'm stuck in the essential: the tuning. By hearing it, it sounds like tuning A, but then the solo does notes that are on the full step down tuning (D), so its better to ask help here; is it actually A Tuning or is probably a 7 strings Guitar a full step down?
