Hey Jackobud,
First of all, nice work on the cab, I really like the cp artwork.
I am in the process of doing the same thing you did: using lusid's plan and making a custom 4 player control panel for it. Roughly what are the dimensions of your cp? Do you have enough space when playing 4 player games? It looks like you just took Lusid's cp and increased the width, which was what I am planning to do.
Thanks in advance
