I have a Line6 POD HD500X and since a couple of days the Analog Chorus doesn’t work. When turning it off and on it doesn’t change the sound of the guitar not even if I set all the parameters of the chorus to maximum. I tried to roll back the Flash Memory and after that to reinstall the latest version, but it didn’t help. If I put the analog chorus in the effect chain in front of the amp it works perfectly, but it doesn’t work after the amp. My question would be if this could be a setup error, and if it’s the case, then how can it be fixed, or is my HD 500x just simply broken?
