Hello there!
I haven't used this effect for a few days, but everything was working properly. I took it out today and realized that all of the effects from the first row are not working. First I thought about the switches, but I rarely used them, and it seems strange to me that all of them (A, B and C) stopped working at once.. Everything seems fine, but none of the switch is working in SCENES, RECORD or regular mode. Have you ever had this kind of problem? Do you think it might be just the switches, or is it some more complicated issue?
