Marshall pedals: JCM800 vs 1959

[Bucksears]

Just curious if anyone knows (yet) if the JCM800 and 1959 (Marshall pedals) have the same architecure, just different part values?
Or are they completely different circuits?
Marshall put all of these in nearly identical configs (same pedal enclosures, all have four knobs), so I'm wondering if there is an internal commonality there.

They're all completely different circuits.

They're disappointingly simple from what I've seen.

Simple can be good! I am often disappointed with pedals with loads of parts - all that work and it doesn't necessarily sound any better than something simpler.
