Yep , The black dial knobs themselves have to come off the front panel, use a pair of pliers to gently yet firmly grab them and pull up.

Subject: Advice for DL-4 home repair
As some of you witnessed, the "record" button of my DL-4 fell apart during my performance at Y2k9. I'm trying to fix the pedal.
I still have all the pieces, and it looks like it should be an easy fix. The trouble is I need to get under the chip board...and it's still stuck to something I can't see. Once inside the pedal, I've undid 4 black screws and one tall hex-shaped screw. I also unscrewed the black bolts around the inputs/outputs on the back of the pedal. The chip board seems to be held in by something in the middle. Could it be the 5 dials for things like modeling type, delay, mix? If so, how do I get those out?
This is frustrating, because if the chipboard was 1/4" higher or more out of the way, this would be a 20 minute repair job.
