I realize those clips werent best case scenario, but I think those sound like poo.
Low chuggy percussiveness with scratchy high trem picking here and there.
I've still never been able to tell if the Fortin Randalls sound that great...They sound like all low endy with scratchy highs, but most of the clips seem to be dinosaur fart low tuned chugs with high meedlies...So I've not gotten any feel for how the mids actually sound because the players only play at the extremes of the fretboard.
I could see them appealling to the Ola crowd, because that tone seems to be their taste.
But man, I don't hear any "tone" in most of that stuff.
