Hi, I have issues with the distortions as well, my POD HD500x it´s not sending the right sound to my amp, it used to do it well but now... I already checked the guitar, the amp and the cables, the only one not working is my POD.
When I start to play the guitar the distortions just sound like theres no effect or it mutes really fast... like if I put my hand on the strings after I play.
Help please!
what can I do now ??
