I had an issue with my 2017 50 watt Yeti's Effects Loop.
I may have been hasty. I pulled out the stock Nik/Ceriatone copy of the Zero Loss FX board and installed the authentic Metro Zero Loss I had laying around. Problem solved. I may reinstall the Nik board and try to isolate the problem. Regardless this is now my latest experimental piece of equipment. Chop Chop lol...
It was also suggested to just try a simple insertion loop.
Thanks for the reply...♪
