I have a pair of open back rack units that I rescued long ago from a dumpster. They have been in and out of the main Atomic Shadow Command Center for several years. So the first phase of the Mobile Command Center project was to identify the various elements that I needed and start seeing if they could fit in the two rack frames. Early on I knew that I needed two signal generators and the EMW-200 mini synth. The Roland SP-404 would stand in for tape machines, which are very heavy. And my trusty Kaoss KP2 would be there because it has a lovely theremin type sound. My Strymon El Capistan tape echo pedal is essential. I don't do anything without that little gem. It has all of the great sound of vintage tape delay units with none of the headaches.
One weekend I drug all of these things on to the dining room table and started making rack ears. That involved hack saws, drills, and lot's of sanding and filing. All done by hand. The circle for the green plasma light was cut out by a shop with the right equipment. Hammerite paint is required. I have used grey and black on various parts.
As a result of the ill tempered customer service there I found a better alternative in the form of a Behringer RX1202fx. This compact mixer has 8 mic inputs, 2 stereo line inputs, built in effects, insert points, tape in/out and more. Very compact. Best of all, no snarky tech support guy necessary!
