Hello, all. Has anyone found a solution that definitely works for instrument level pedals like the DL4 in the loop? I can get it to work without any breakup by lowering the loop level, but I still get a pretty good dulling of the tone and drop in volume when I kick it in. I've read up on the Ebtech Line Level Shifter but I don't know if it would really solve my problem. Thanks in advance for any help.
