Make sure that the pedals are properly calibrated as described in the UM. They should go 0-100 over the full range of the pedal – if the pedal only moves a little to cover the full range, this could be the problem.
Then, try pushing the jack in and out about 10 times at each end to clean the contacts.
If that does not help, try another cable.
If that does not help, and the problem mainly applies to one unit,, send it for service (support@eventide.com).
