Don't ship anything fedex or ups (like an amp) without at least 2" of heavy/stiff foam all the way around. reason? if THEY drop it, they'll say the damage is still YOUR fault. all of them are terrible. learned from unpleasant experience. Some folks have caught onto this. I ordered a 1x12 cab from a shop (earcandycabs - fantastic!) and they sent it in 2" of foam all around, shrinkwrapped, with a packing label on it. take that, ups!
