How do you have everything connected to the ML10X? A photo or diagram would help to further troubleshoot this.
A common misunderstanding is to connect the INPUT and OUTPUT of your pedal into the same loop with a splitter cable on the ML10X. Each loop only functions as either a Send or a Return. So you need to connect your pedal’s Input to a Send port, and your pedal’s Output to a Return port.
Hi James, that was not the issue in the end. I was connecting the input and output as you described, but I just think the issue was somehow on my side as my setup is quite complex. I created a separated and more simple setup and the ML10X works just fine!
