Pigments may have influence on the tone but then again, who can hear the difference?
I know that PL is highly compressed (or whatever it's called when everything is really loud), but I think the tones are great - the bass tone in particular. The bass can be heard clearly (unlike The Odyssey or V), and Lepond finely achieved his silky-smooth live tone on a studio album.
I can't even imagine how many times he might've dubbed that one opening Power Chord in Set The World On Fire, but I'll go with 12 times.
