Hello all, I bought a spider IV 75 with the mkvII footswitch off of facebook marketplace. When I switch channels, a lot of times it does not switch properly. For eg if I switch from distortion to clean and back to distortion, it will sound clean both from footswitch and the knob. is there something I can try? what can possibly be wrong?

how do I do that? I am very new to this stuff?

Hello, I have a spider IV 75 using a fbv mkII footswitch. Whenever I change the channel to a distortion channel from clean, the channel switches to the distortion channel but the sound does not. It will still sound clean and not distorted? Does anyone know of an easy fix? I hope my hardware is not broken. I bought it used.
