Anybody know what causes what seems to be an energization problem with these PDS pedals? The pedal will turn on instantly and light up, but the effect doesn't function until maybe 10 or so seconds. Switch to a different delay timing, and the issue starts all over. I've replaced all the aluminum caps but the issue pertains. One PDS pedal in the past had the same issue yet corrected with new caps. I have another chorus pedal of a different brand that has the same issue, but the caps are also fine. What gives?

From a Reverb posting for a PDS 8000:
"An interesting tid-bit-- when you first power these PDS-8000, they go through a 15 second cycle of clearing out the ram chips. Digitech had to add a warning flyer to later revisions because people thought they were broken. Just power it on and give it a few second to line itself up."

I thought of that, even though that's a weird explanation. However, after the effect finally sounds, flipping the delay time switch makes this "reset" time start over again. That certainly doesn't sound like it should do that. I have to check if it also does the issue after cycling the effect/bypass switch.

Hmmm, just worked on a PDS 20/20 that does the same thing.
Also does it when switching between Flange/Chorus/Delay.
