The tabs for this album are a mix if B Standard (B-E-A-D) and Drop B (B-Gb-B-E) tunings. Things get quite music theory spicy here though... (remember: the point of music theory and transcriptions is to make things as tidy as possible to read)

The tabs are written out as if they're in E Standard and Drop D despite the actual tunings and this means that all keys are written out as if the bass is tuned up to those more "normal" pitches. While this is to make them easier to read it has the knock on effect of there being some odd looking key signatures on the page due to the harmonic choices that Robb makes when writing his riffs.

Notes about these will be in the individual song details sections below as needed.
