Just got a flight case for one of my Aguilar 4x10's, the pullover type, so the cab sits in a small two inch high "tray" lined with foam with the wheels on the bottom of the case. Standard flight case arrangement, it seems. Case has a bit of history, it was owned and used by Trey Gunn on the last King Crimson tour, still has "Trey Gunn/King Crimson" shipping stickers on the top. Unfortunately, the lower ports of the cab are covered by the lip of the lower part of the case that it sits in. I assume this blocking of the port is going to cause problems with the sound and performance of the cab, right?
