Thon Case for TC-Helicon is an excellent case that provides real protection for my TC-Helicon VoiceLive 3 Extreme. The case is massive and sturdy, and sponge inside also, so you can really trust it.
The only modification I would suggest is that it would be a good thing to add a centimeter or two at the part of a case where TC-Helicon VoiceLive pedal has its inputs for XLR cables.
I wanted to use this case in a way to remove the cover of it and use the pedal while is in a bottom part of a case.
The problem is that some cables have a long neck.
I am from Croatia and English is not my mothers language, so I'm not sure if I'm explaining that right :)
Anyway some XLR connectors are longer than the others.
At the time when I bought TC-Helicon VoiceLive I used to have cables with long version connectors which makes impossible to connect to a pedal while it's in a case, so I have to lift it up a little bit which makes connectors to flex, so finally I had to take out the pedal from a case while I'm using it.
After a while, I bought cables with a shorter neck, so I don't have these problems any more, but it would be better if I didn't have to spend an extra money because of that.
But in the end, the suitcase is very reliable and it pays to invest in it, especially knowing that keeps your very valuable pedal safe.
