Looks very similar to the Rack I reverse engineered the spec's for and had Tracy over at SSP build for me for a friends project I did a couple years back. I custom modded a GCX Audio Switcher just for the project.
Hey Waldo I know this is an old post but I'm curious, what mods did you do to the GCX switcher?
That's a sweet freakin rack you made there, badass, I'm sure your friend is totally stoke on it. You said you built it a few years back, is he still using it today?
