I believe for the distorted "lead " section they used a marshall guitar head on the album, I may be wrong though.
The easiest way I have found to cop that tone is using the distortion in my Morley Pro Series Distortion/Wah into a tube guitar pre-amp with a Marshally tone stack, and then add some reverb.
There must be lots of tube drive pedals that can easily cop this tone....I just happen to have more pres than drive pedals.
