If this is true, then I have two comments:
1. Wouldn't it be reasonable to expect to see that Helix only works with SOME Variax models in advertisements and official tutorial videos on sites such as YouTube? I can't remember ever seeing any distinction made between which models work and which don't in any of the many places I looked at before making this expensive purchase. That distinction may be made somewhere, but I've never seen it. All references to "Variax" I've ever seen simply say "Variax".
2. The 300 I mentioned is one of two Variaxes I have. The other is a left handed 500. The 300 is actually a custom-made guitar using the guts of a 300. I needed a backup for my 500 and scoured the internet trying to find another left handed 500, without luck. So, I had to buy a right handed 300 and have a luthier build a left handed body to put the electronics in. Line 6 did make the long-discontinued 500 in a left handed model for a while, but has (as far as I know) completely ignored the needs of left handed players since. If any of the newer Variaxes were made left handed, I'd probably have two or three of them now. Instead, I have now bought an expensive item that was advertised to work with my existing guitars, and have to wrote to this forum to find out that it doesn't. Seriously, that's adding insult to injury.
Why doesn't Line 6 make at least ONE current Variax model in a left handed version?
I'm sorry to sound harsh, but left handed players get treated pretty badly in the guitar world, and I've had almost 50 years of it.
