Not fair to blame Line6 on that kind of damage. That happened after it left the factory.
What evidence do you have to support this statement? The JTVs are packed really well for shipment from Korea - for that kind of damage to the guitar to happen in shipping the packing would have to be damaged or destroyed in an obvious way, Oleus said the packing was secure and I am sure he has a better idea whether the damage was caused in shipping than anyone else here could possibly have, and writing the problem off to shipping damage makes posters here sound like they are doing damage control for Line 6.
The fact is QC at the factory is crap.
I am not at all surprised to hear they let a guitar go out with a busted tone knob after reading about the problems so many others have experienced and after buying a JTV of my own. My guitar never would have made it out of the factory if it were built by Gibson, Fender etc. - not even as a "second" - it would have been destroyed, at least the neck would have. Even the cheapest $99 Squiers and Epiphones have nicer necks than the one on my $1299.99 (I got it for less) JTV-89 - mine is the worst neck I have ever seen on any guitar built within the last 30 years.
If Oleus' bent tone knob were an isolated incident I could write if off, but it is just another story confirming that now is not the time to buy a JTV. I really hope Line 6 gets their lollipoppery together someday, I still think the concept is brilliant. But for now purchasing the guitar is risky, and no amount of the "haves" (those few who were lucky enough to receive fully working JTVs the first time) dismissing real problems that the "have nots" are experiencing (unlikely/improbable/implausible shipping damage) is going to change this. Really, it is the opposite of helpful.
I recall complaints of smashed/bent knobs and controls that the owners said could not have been caused in shipping being discussed here in the past, this is not a new problem.
Add it to the pile of reports of bad necks, bad bridges, ghost notes, guitars bricked during routine firmware updates, dongle that only works when it wants to, switches going haywire... what am I leaving out here...? Take all that in and the JTV looks like a pretty bad investment.
And like clockwork here come the lucky few (maybe 10 so far?) "haves" who received a fully working guitar the first time rushing in to say "I didn't have any problems with mine" for the hundredth time, because of course one guy saying a hundred times he had no problems gives the appearance there are a hundred guys who had no problems, and another poor sucker considering purchasing a JTV reads this and thinks he has a shot at getting a functional guitar... and sure enough here comes that same poor sucker again later with yet another tale of Line 6's total QC failure. Closely followed by those same Line 6 defenders writing off the problem.
Circle of life...
(someone PLEASE edit this video in a humorous manner, maybe the monkey could annoint the baby lion's head by spelling out the word "sucker", then hold up a JTV for all the other stupid animals to see/freak out over)
