Waldo thank you for the photos and especially the close up of the pedals with the settings indicated. I'm bemused to see that my OD-2 settings were nothing like Jerry's - not even in the ballpark.
I adjusted my OD-1 and OD-2 to match those settings and compared the sounds with the '93 show clips you posted and I'm damned if the sounds don't appear to be reversed. The OD-2 as pictured is significantly gainier and toppier than the OD-1.
I can't explain it and I don't know what's going on. Maybe he swapped the roles of the pedals at some point but didn't swap their positions in the rack? Maybe I'm completely out to lunch.
I would be most grateful to anyone who has actually run this pedal pair if you could kindly chime in with your personal experiences.
