Sure, components fail, more so when they're stomped on
Which is why I generally buy mass-produced electronics *new* w/ warranty, because you never know how used & abused a piece of *used* gear is, unless there's damage & wear/tear clearly visible...
In reality there's always life expectancy ranges for components too ~ It would be interesting to know how many cycles Line6 switches are rated at, if any one knows the make/model it wouldn't be hard to figure out...
I know that Roland FC100 foot controller switches would fail somewhere after a couple of years of constant use, which is why I bought a bunch of replacement PCB switches & was skilled at fixing them when they went *bad* back in the 80s & 90s, when I had a GP8
There's also relays that can wear out, but usually those have a higher cycle life, but not always...
All I'm really saying is people that are not keen on repairing switches probably should stay away from *used* gear known to fail after a couple of years, which there is oodles of info across the net to confirm with Helix switches.
I believe you'd find a lot less corroborating to confirm the existence of Bigfoot, but I've never looked into that
Well, since Fractal controllers are separate from the main unit, they're probably easier/safer to repair then a workstation built into a floor unit, but no experience with that either
