Just wow.
And this is exactly why I avoid buying any more Line6 products, and god knows I've owned a lot of them.
Imagine if any other device required a special unique proprietary super expensive thing, just for basic maintenance.
Imagine if you needed to spend 100 just for a standard usb cable to flash any other device (computer in fact, and that is what a Variax partly is).
Yes, it is absolutely Line6's fault, and I promise if people banded together and pressed the issue, the lawsuit would be won easily. I'm an ex computer industry geek. This happens all the time.
So, do nothing about it. I really don't care. Not my circus. Not my Monkey.
As a last word of advice though, companies actually pay huge sums of money for research into customer needs and complaints, and they understand it's of value. One of the best bit's of advice I've ever been given is to tell someone when they are failing at something. You don't do them any favours by keeping it a secret and letting them live oblivious to it.
Have a nice day.
