Cool stuff. I'm not much of a pedal board guy, though am a DIY addict.
Built this whole road case setup for my expanded Axess FX1 controller just in case I landed a world tour to the next-door neighbor's. Got most all the stuff from Penn Elcom. I had all of the construction pics on Photobucket (GONE!!), I think I have them on an old laptop, but it was surprisingly easy to make.
The internal triangular thing (wife called it a planter box) was to protect the connections from wayward feet.
The silver box on the left was a custom piece I built that handled the whole board to the rack with one 7-pin XLR cable, including MIDI, Phantom power and tuner signal switched remotely. There was no audio on the floor.
I still have the case, though pulled down the setup after ~10 years, as sold off the FX1's expander (for the same price I paid in 2006), as I'm switching to an RJM GT22.
The whole setup weighed about 35kg - yep - a real bitch to move on my own (the things we do).
The EBMM pedals had the toe switches for enabling Whammy IV and Wah (over MIDI), the dB Instrument amp thing allowed the wet and dry signal volumes in the rack to be varied independently (also over MIDI), and clock with the Polytec 34One.
