I built a looper gig flightcase solution to fit a Boss RC-505mkII looper, Eurorack gear, power supply units and all the cables inside a Flyht Pro Case Universal flightcase. This was my only hope with the proper depth for attaching the looper with velcro on it, if I just cut the tray shorter. And it worked perfectly! All the stuff fits in with the lid closed. This saved tons of time setting the rig up at a gig.
