Same result in and out of the enclosure. Works as expected except no gain attenuation on the attack control. Working through the traces per Jim’s advice…

So I’ve confirmed the grounding is solid, off board wiring is solid, and have worked my way through the traces for continuity then checked between the component legs and the board traces and I can’t locate a fault. Since the pedal works fine save for the attack attenuation I’m guessing there are no bad parts on the board. Sort of stumped now…

Check continuity between attack pot lugs 2&3 with knob maxed - if there's beep, then try reducing attack. When there's still continuity with attack reduced, or when there's no continuity with attack maxed, then it's pot wiper shorted or damaged. Easy to replace pot and see anyway.

Thanks sledz- looks like the wiper is good. I’m gonna recheck the wiring from the pot to the board a bit later today…
