I had the same issue when I first tried using wahs in Helix, everything felt kinda flat and not expressive at all, but it turned out I was just treating it too “plug and play”. What really helped me was putting the wah before the amp and drive, not after, and then pushing the level a bit so it actually reacts instead of sitting dead in the mix. I also stopped using stock ranges and started adjusting heel and toe until it matched how I actually move the pedal, that made it way more “talking” and less dull. Chrome Custom with a bit of Q tweak works great for me, way more alive. And honestly, dialing in a good wah reminded me of how I approach stuff like bonus setups, where you don’t just click and expect magic, you go step by step and understand what each part does, kinda like I saw here https://jeetcitycasinoreview.com/bonuses/ where everything is layered and only really makes sense when you actually dig into it a bit. Once I started treating the wah the same way, it finally sounded right, especially on headphones, way less flat and way more expressive.
