A lot of drum techs will set up the kit for themselves. It’s a natural thing for anybody to make it comfortable for himself or herself. For example, I sit a little higher than most drummers, and sometimes techs have forgotten to raise my stool when they’re done. You’ve got to remind them that they’re setting up the kit for where you sit. If you don’t, and if that’s screwed up even one little bit, you can be in trouble when the time comes to play.
