This is my expression pedal: SONICAKE Passive Volume & Expression EXP Pedal, Mini Guitar Volume Pedal – Vexpress, which conforms to the Eventide specs and calibrates 1 to zero. I actually have two of them so tried swapping the first one out for the second – no change. Here’s the strange thing, if I leave the pedal up and change programs, the setting for the second program is also changed, but not by a set amount. If I bring the expression pedal all the way down, the other programs sometimes go back, but not always. The algorithm is delay and I don’t think it’s jittering, it’s too precise. Flumoxed.
