After going through many variations of cases for table top synthesizers and other equipment for travel I’ve found these cases fit many things:
“Coleman C006 Soft Messenger Bag Cooler” priced as low as $10.58 each
They are heavily padded, water proof (need silica gel in humid places and leave the zipper cracked), well made, semi-rigid exterior, have a shoulder strap (for minimal gigs) and stack nicely inside inexpensive Rubbermaid tubs for travel by train, bus or car.
a short list of gear that is known to fit inside:
Smaller Jomox table tops including Time Woven Filter Matrix plus extras
Bugbrand Red Box effects / processors in original frames
Blippoo Box and power supply
Sound Devices 442 plus power and some cables
They fit 2 six packs of regular sized beverage cans in their normal life for an idea of inside dimensions. I’ve tried some other lunch pale cold bags for equipment, a lot of them work well, but these are the best so far.
Leaves more funds for modular :>)
Any other unorthodox case ideas?
