Bump for a note. I’ve used the SONICAKE Vexpress Passive Volume & Expression EXP Pedal for various uses including expression, midi controller and volume. When I simplified my pedal board I just used it as an expression pedal and thought perhaps I should get something a bit more robust, so ordered the Dunlop, / Volume X Mini Pedal (DVP4). While it connected, calibrating it only went from 0 to 79 and I tried several times using a TRS cable and plugged it into the pedal first, then the H90 as instructed. Unless someone has thoughts about what I might have missed, I’ll be returning the Dunlop.
