This is sad. I join the cult in 2019 when I got a Variax Standard which was made by Yamaha. I used the analog 1/4" jack to connect to my existing gear. I then bought a POD xt Live to connect digitally but that model is outdated. I recently bought a Helix and I love it with my Variax. Line 6 should sell these as a package and create more out of box presets that take advantage of the different models of instruments the Variax provides.
I've been having trouble with the connection on the guitar where it cuts out when moving around on stage. I bought a new cable but that didn't fix issue. It looks like I may have to replace the whole Jack assembly.
I am looking at a used JTV-69 on Reverb but I am concerned that if these aren't supported and I have problems with it, I won’t be able to get it fixed.
It would be great if Line 6 could get other big name Guitar Manufacturers to buy into using their technology but I think most of them are competitors in the pedal market and won't play nice.
I think another down side to using VDI to go full digital is the fact you can't go wireless.
