Wow those are pretty. Any 1.5 mods to go with them?
I only have 1.25x and 1x mods.
Is that a 10 key , or what is that with the black blue brown switches on it? Looks like a nice test bed for switches.
Those are switch-try PCBs. There are 2 different styles. They come with just the switch bodies presoldered. You can order some blank relegendables with them. I have 9 used ergo-clears, 13 new Grey 39, 2 new clears, 21 new platemount blacks, a
shitload of new browns (~2000), and a limited supply of new PCB/plate-mount bottoms that I could swap.

You can label them with blank relegendables.

3700 style switch-try PCBs.
My 3700 is NOT for sale!
