Amp switcher: control matrix design

Background story: https://fosstodon.org/@awai/114093865582292065
Project overview: https://fosstodon.org/@awai/114110547162586997

Now for the final part of the design phase: the command PCB!

The idea here is to provide a simple way to select the amplifier to be used, so a rotary switch feels like the best solution. As I don't want to bother with a power switch, I also decided the 1st position will act as an OFF position.

It's that time again where my brain needs a new, different project

But first, a bit of background story: I've been playing music, and mostly guitar, for over 3 decades now. Being quite a nerd, at some point I started looking into guitar-related electronics, and eventually fell down the "tube amplifiers" rabbit hole.

I grew passionate about tube amps and even built my own; most were sold over the years but I still have a few, and recently bought a couple new ones.

Why do people in #amplifier review videos play back example music to listen to?

I mean it's not that my device is able to reproduce their sound experience.
