There is no settable calibration of the external expression pedal on the HD500 or 500X, or any of the L6 units that use external pedals..
I just purchased the Mission Engineering EP1-L6 expression pedal, so am just getting into messing with it. It is basically a pedal-operated 10kOhm potentiometer. it has a rack & pinion type mechanical gear connection like my old volume or wah pedals from years ago.
If yours is similar, you may be able to go heel down (open up the action of the pedal) and disengage the pedal ratchet a little from the rotating pot shaft, and rotate it a few gear teeth positions one way or the other so that it's travel is slightly one way or the other from where it's at now. It might help you get it into the range you want.
