Thought I would share an image of my live rig. I took a circa 1930s or 1940s suitcase that I bought at a tag sale for $3 and ripped out all the contraptions inside. This is the most over designed suitcase I have ever felt. I swear the panels are made of wood. I made a thin board that covers the melodicas during transportation. The rubber band keeps the melodicas from falling out. The pedals are sitting on the HM-36 case. All cabling, microphone, pedals, etc, fit in the suitcase. I walk in carrying one suitcase and one mic stand. I sit in a chair when I play, and the suitcase is on the floor next to me so that I can swap out melodicas and change pedal settings during the performance.
I am also working on another rig that uses high quality rack equipment in an SKB case. Again, the equipment and melodicas and all cabling will fit in the 6-space SKB rack, which has a handle and wheels. I will post a photo when I get done with this ever changing rig. It is coming into focus, and right now, I am thinking the rack equipment rig will be the better of two.
