Hi All,
Many thanks to @hdoran and many others that put here helpful info.
It took me a couple of days, but finally I managed to configure the FCB1010 with my HX STOMP with the expression pedals and its wonderfull, kinda of magic ;-)
And I have an improvement to use the WAH function:
You can USE the SAME Expression Pedal for managing the WAH and ALSO for Bypassing it.
Yo only need to put the Bypass for EXP1 (for example) set to 0%. and SAVE YOUR PRESET WITH IT BYPASSED. AND IMPORTANT: Exp Fubnction in PRESET MODE (Global Settings)
Since this, each time you recall this preset the WAH is off, and at the moment you move the EXP1 the WAH its activated and ready to use.
To deactivate you only need to let the EXP1 at the minimum position. And no worry about desactivating it accidentally while using it, it has a 300ms latency time for bypassing. For me its enough to use it normally and only deactivates if I put to the minimum and quiet.
Hope it helps to Somebody.
Regards,
