Standard 12mm hole SPST momentary (non latching to off) foot switches you can get from any guitar FX pedal supplier. They don’t light up but if I want to add an LED light to each I could, but with no mechanism to toggle them based on GPIO activity, I haven’t added them.
Retrofittable led lights here:
Sorry I was looking more at 16 grid buttons.
Just ordinary low profile 24mm dia arcade buttons. Seimitsu PS15’s IIRC. No they don’t light up.
What a nice work, @PunkPrincess! Big Congrats!! I can’t wait to hear your noize … 
Thank you. It sorely needs a case which, when this is signed off as done, will lead me into buying a Desktop CNC router (why I backed away from the pedalboard idea)
Will you use it on stage …?
Better yet, tune the router pitch to a MIDI keyboard, so you could actually play it! That would be so useless and so cool…
Building a few other sound devices while I waited for the CNC machine to arrive. Now here, been learning feed rates and bit types and materials next so cautiously moving ahead, but I did prototype the top of my Zynthian enclosure in 3mm ply as a sort-of proof of concept.
I do like the bigger screen,
This is great… I also built a teensy midifighter. I originally did it a few years ago and now it’s due a refresh. 3d printed parts are waiting somewhere between Europe and the UK at the moment. Updates soon 
Keep up the good work!
