dmaan Posted February 23, 2021 Share Posted February 23, 2021 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?

psarkissian Posted February 23, 2021 Share Posted February 23, 2021 Which foot switch? Quote Link to comment Share on other sites More sharing options...
fflbrgst Posted February 25, 2021 Share Posted February 25, 2021 Does the amp display show that the amp actually changed channels? The first thing to do would be to back up any of your user-created patches to a computer via the FBV and a USB cable. Then do a factory reset and see if that fixes the issue.
