So I have to stack amplifiers on top of speaker cabinets (and other amplifiers) that have handles on the top. I will use wooden blocks. Ethan came up with the very smart notion to put suede leather on the blocks so the blocks wouldn't be all slidy and would also not hurt the finish on the nice wooden cabinets.
This article in EM on processing while recording is... actually quite helpful. I woulda never thought of that. You can apply software effects while you're recording. Rock on.
