GH:WoR pedal and a GH:WT pedal? I know there's 2 outlets in the back that both are purple which makes me think they would both be able to use the pedals, but I plugged in a universal pedal in the second slot and it didn't work. I then ordered a GH:WT pedal to see if it will work, but it hasn't arrived yet and I kinda want to know ahead of time so I don't waste 30 minutes trying to get something to work. Any help?
