What are you all using to ship your amps back to HQ? I have a MKIII that is due for maintenance and I am trying to figure out what to ship it in so it isn't damaged in transit.
ship the chassis only. use cardboard and slabs of foam from other packing to make sure there's at least 1.5" "solid" protection around the chassis on all six sides, and that it can't move at all. don't use any loose fill.
