Howzit man,
The CC uses SMD boards making it very hard to mod, especially if something goes wrong.
I also see they haven't released the factory schematic so you'd be flying blind.

I rate probably not the best pedal to mod. I'm not too familiar with BDD delay circuits, but I doubt simple mods such as replacing a capacitor would have a significant effect.
Regards,
Matt.
