Both the first two albums were recorded with four-strings (WDADU on a Sheehan-ized front humbuckered StingRay, and a Spector NS-2 for Images & Words) so apart from the downtuned beginning of "Take The Time" there's no problem there. If you've got a 5-string you have the range to play most everything else with some positioning shifts - JM has stated that he jumped to a six-string for the ability to play more positionally as opposed to range and racing up and down the neck.
...yeah, 'cause he doesn't do
that in the slightest.
