You can set the toe position of the wahs to be whatever value you want. The lower you set it, the less harsh it will be. This goes for all the wah models.
Unfortunately, no matter what position I set the wah to, it is far too harsh and lacks any gradual change, regardless of model. The change is not linear using the expression pedal - it's mud or it's piercing. Not sure if the linearity is part of the model or the pedal. I'm assuming it's in the model since the volume control is more or less linear.
Also set the mix value for the chosen WAH to around 50-60% - it will sound far more natural. I do this for any WAH pedal now and it sounds so much better and like a real WAH. Adjust the mix to taste - but do not leave it at the default 100% as it does sound too shrill at toe down and too muddy with toe up!
I've tried pulling the mix down but still can't find a sweet spot where it sounds natural. It seems like the mix is also very sensitive for the wah models; it's either very full in the mix or transparent in the mix with very little room for fine tuning.
I'll need to play with these settings to try and dial it in
