Wow. I'd be interested in seeing the data behind that statement.
Seriously - let's try to keep things realistic. It's true that some users, including yourself, prefer v1.9. You have stayed with that version and are happier. Nothing wrong with that. I happen to prefer v2.0. We're both happy. Where's the 'fiasco'?
It´s realistic to say that a big part of users that "are happy" of the 2.0 firmware are also "line 6 experts", to which they were apparently given the task of creating positive reviews on the forums. However, it is easy to verify that the update is a complete failure on many levels; to mention a few of them: Telecaster, Stratocaster, ES-335, ES-175, all of them sound worse in 2.0. The acoustic guitars sound out of tune, the POD will not work anymore as interface for workbench, all models are out of adjustment, even including individual volume of the strings. Delay and popping noises changing models (when this did not happen before) Not to mention the bugs in the upgrade process. All this is not representing a fiasco for you?
Then do not know what they should have done to make it so for you. Maybe if the JTV was disintegrated with the new firmware, or was wrapped in flames, or maybe it exploded. Okay, it do not get to that point, but for me it is enough to consider all the aforementioned to say JTV 2.0 Firmware is the biggest fiasco on the whole history of line 6.
But I do not mean to be grumpy , I'm simply stating what I think is pretty obvious . And I 'm glad you 're happy. I 'm not as much as you, but I still have a small hope that someone fix this terrible mess .
