What tuning are they using on the new album? The low end sounds really tight so I'm thinking they are using 7 string guitars. Is this correct? Im trying to tab out Lost.
 
There are 2 songs with 7-strings. Still In The Water and The Curtain Fall. I believe the tuning is ADGCFAD. For the rest of the songs CGCFAD.
