No doubt he has a Pedal board for what ever he needs at the time BUT I was referring to his comments in this video...
At around the 16min mark, he talks about using the HX effects on his pedal board for his current clinic tour because of how it works with his PT15 and also talks about using a standard Helix with his PT100 on a clinic tour a few years ago running it 4 cable method. He also says that he also has a helix Pedal board set-up with several pedals connected in the loops and full of praise for Helix.
Again though, this also proves the point I was trying to make though that devices like Helix are a great tool for musicians to use in any capacity and situation that suits them best. On his clinic tour promoting the PT15, he chooses to have a HX effects on his pedal board, a few years ago, it was a Helix floor with his PT100 on a clinic tour. Its about using the right tool for him at the time and that Helix obviously has been the right tool for him for certain things. The fact that he feels its good enough to be the tool he wants/needs at any time shows that its good enough for a professional working musician. It may not be a permanent addition on his pedal board for every situation but it doesn't need to be. It maybe only used on Clinic tours as the 'best' tool for that use for him and for another, they may find its the best tool in a different situation - of course there are some who may have other tools and don't want/need something like a Helix at all but all I was saying is that its about using the best tool for job and that will vary from person to person and devices like Helix are now good enough for professional working musicians.
I know its not the best tool for you or your needs/situations but that doesn't mean they are bad, sound bad etc.
