Hi Partev,
I've now got hold of a USB device.
When I plug it in, I get a stable green light on the USB end of the device and flashing red light on the ethernet end.
I don't have a battery for this guitar - it was bought second hand.
When I read the instructions for flashing the firmware on the Variax, it says I need a battery in the guitar but other users have told me I don't need this.
Can you clarify please?
Are there any other steps I can take or do you think it needs to go in for a service?
Thanks.
