Okay,...so my SA dual expression pedal finally arrived. The plan was to use the mini plug for my C4, and the 1/4" for my HX stomp. However, the HXS doesn't seem to be happy with the SA exp pedal. Any advice on helping these two get along with each other? Tried some quick programming with it last night and there were a host of problems. For a simple wah on the HXS, I could use my old dunlop mini to turn the wah on and off. With the SA, it turns it on, but not until the end of the sweep. It also wouldn't save and recall. On top of that, it was controlling the frequency range of the wah, not good, i.e. changing a sweep of 180-1.9k to 30-500. I'm just a bit frustrated here. Cue an Obi Wan to come rescue me please! I haven't even tried messing with the C4 exp yet. Thanks in advance for any insight.
