Doing some research I came across this:

"good news is that there was an identified issue with some of the footswitches that have been given a lifetime warranty...

you'd need to check your serial number though... personally i'm not aware of the affected serial numbers... but the info is in the forums if you search."

and this:

"There is no public document we can show to prove to you that they are covered, but when you take the X3 Live to them, tell them to go over Technical Bulletin #44 for the X3 Live footswitch light pipe replacement in the service manual. These tech bulletin repairs are considered warranty repairs even after 1 year."

I had already taken my x3l in for one repair on the switches. Obviously mine is one of the "affected serial number" units if there is such a thing. If this is true, could you just switch mine out with a "not affected serial number" unit? It can be a used x3l. I don't care. As long as the buttons stop breaking.

Because obviously the initial repair I had done under warranty was a short-lived "fix"
