I just pulled my LT-based live rig out of storage, where it's been since last March due to COVID. And it doesn't sit flat! I can't remember if it did this before I put it in storage - it's been a realllly long year. Anyway, the upper left and lower right foot sit on the floor, leaving it to rock about 1/8" between lower left and upper right.
I can easily shim the feet on the corners that rock, but before I do that I wanted to check if this was maybe a known problem with a simple solution (loosen and retighten certain chassis screws, etc.) Thoughts?
