I really think the more you educate your users on a product the more likely they are to use advanced features. Not everyone that uses the Kemper or the AxeFX knows what they are doing for sure but you have to always make sure there is something there for those who want to learn more.
I'm not one of those people that fears bricking my device so I do beta updates and test features if they are relevant to my interests. As long as betas are setup behind a qualification wall you really don't have to worry too much about the public. Betas attract people that like to see change. If you want to make sure to keep out the people that don't read user's guides you just have to make sure they agree to be a tester and that they understand the rules.
Between Guitar Center, Sweetwater, and local music scenes, there is always alot of talk about Line6 products.
Houston has 5 locations. That is more than in any other city here. Texas has 50 stores. There are 3 of them that I have spent quite alot of time in. And I regularly get updates from them and Sweetwater.
I also work for IATSE and work stage, conventions and theaters. I do backline support and I've talked to touring crews and conventions about Line6 products as well.
