Double Pythagoras Delay and Reverb project - any ideas?

[Danbieranowski]

Hey all,
Here’s what I’m working on right now, and I was hoping someone might be able to point me one way or another for a mod. I’ve got dual Pythagoras boards in series, one running the D3lay eeprom into one running the Threeverb eeprom. The delay and reverb combo sounds AWESOME (hear it below), but I was hoping to add in a momentary switch somewhere in here to do something cool. I don’t really care whether it’s runaway delays or slamming the mix to full on the reverb to make things ridiculous. Basically anything fun. Anyone have any ideas how I could accomplish this? I tried doing the runaway delay Magnetron mod with various trimmer values with no luck. All I could get was a very slight addition to the feedback that was barely noticeable. I also tried doing this with the mix pot of the reverb with various trimmer values but no luck. Anyone have any ideas?
Here’s how it looks inside:

Here’s how it sounds:

I like the way you look for something odd to toss into the really cool mix. One thing that might be fun would be to tap the output from the reverb/delay combination through a momentary footswitch/trimmer to cycle back into the reverb input.

Oh that sounds fun!
