thanks for the response silverhead and pierm, I am able to use regular cables with the hx stomp and it works fine. I can use the wl20's on my guitar and amp or audio interface (focusrite 2i2) and there is no problem. I do get the analog pass thru which tells me the wl20's are communicating, then they stop when it is booted up. I am using all original parts (power supply is the one for hx stomp). So, they are working just not when it's booted up. I have the latest firmware update as well. I tried pluggin in the wl20 after it is booted up and it worked once-but I couldn't repeat it. So, perhaps it's the channel it's using or there is something in the programming of the hx stomp that goes into by-pass mode. I'm leaning on channel issues with the wl20 since it did work once. PierM, thanks for the info on the mono adapter I will get one and try it and get back to you.
