spent the day making the first in a series of videos on drum tuning for the Puremix website. puremix.net is an advanced audio tutorial website - basically an instructional website for producers, engineers, and musicians who do their own recording. it was great thinking about the subject from the standpoint of a non-drummer; the info they need to do the job, and how robust a subject it is, even though it seems simple to someone who has a lot of experience. check out puremix.net for the video and for lots of other helpful videos about recording and production.
