I've have used over 1000 different switches on gear over the last thirty years. I've had to lubricate exactly zero of them, and had exactly one switch fail on me previously after a guitar cab got dragged across my pedal board physically damaging it.
Now my basically brand new FM9 has 4 crunchy switches and one that has completely failed already. This thing has been babied the two months I've owned it, as it is by far the most expensive piece of gear I've ever sat on the floor. Fractals track record of building damn near military quality gear is the reason I had the confidence in the product to invest so much into such a crucial piece of gear that will spend it's life on the floor. No gigs, has only left the house once as I use my Ultra at practice still as I'm still creating patches for the fm9.
So it seems fractal got a batch of bad switches, and it's more then just the physical crunch and will lead to switch failure sooner or later. ( How can it not? It you feel these switches grinding, you're removing material like sanding or filing would, and that debris has to go somewhere, and eventually cause what I'm experiencing.
So I'm outside the return window, but really second guessing my purchase now. Not because it doesn't sound glorious and is easy to use, it's both those things. But if a $5 component takes down my $2000 rig after two months of light duty home use, what am I going to deal with in two years when my unit is out of warranty as well?
