Most of your comments are absolutely fair and I agree with them.
However the "say nothing unless its nice" arguement doesn't apply to consumers in relation to (often) expensive technology in a very competetive market. We, the consumers, would be a walk over if it did.
Assuming Line 6 personnel occassionally look at these forums, they are probably an important way for them to find out what their loyal customer base want and feel about old and new products.
Yes we could all be apathetic and ignore the things we don't like or want to see improve. I'd rather Line 6 were aware of what their "community" wants. If I hated Line 6 gear and owned none of it, I wouldn't ever have signed up to this forum. Its not about "negativity".
