POD HD PRO X No Sound in POD HD Posted April 29, 2018 I was recording on my Pod hd pro x yesterday on my guitar(as i have countless of time before). Suddenly today it stops working. The device turns on and I can hear sound from my computer, but it won't get any signal from my guitar. Not even the tuner. I checked my guitar and the wires. I have no idea what happened or changed. I would really appreciate some direction.
