I updated the firmware to the POD HD and Variax 10 times, but it did not help. The sound in the headphones is not, when you turn on the tuner sound is not. Maybe you can do something else to try?
POD HD PRO to control the Variax ? Maybe it's not available for the POD HD PRO ? I need to switch the preset on POD HD PRO-change guitar model on the Variax...
I would try it with nothing else connected except power supply, VDI cable and output to amp or speaker. You want that I connected the Variax to the input of the amplifier ?I'm from Russia,use the translator to communicate. Sorry to ask again...
