That’s a tough discussion. You might consider rolling backwards through this thread for some insights as to why.
You're thinking of the 4 and 5 button switches, where there is a microcontroller involved...but I believe with the early 1 & 2 button, they are pretty straightforward switches like most.
Even if there is some "processing" in the amp...as long as the switch and XLR connecter are wired right, any 1-2 button should work.
In my 1 & 2 button switches...there is nothing more than button(s) and LED(s).
