Well I picked one of these up yesterday and here are my thoughts on it.
I'm just tuning a cheap tama metal works 13" snare. The head on the top is around a couple weeks old and the bottom head is still in really good shape so I didn't replace it.
Doesn't matter about the bottom head anyways, when I checked it with the tune bot it was in tune.
This head ended up being +/- .2 Hz at any given lug.
Anyhow the top head:
Started with a pitch of 338.4Hz at lug one (8 lug).
Anyhow, for some reason I had to be satisfied with a variance of +/- .4 Hz. I just couldn't seem to get everything exact. This was after measuring and placing a small x at a distance of around an inch into the head from the lug.
So I'm thinking it might be a limitation of the drum and not the tune bot. When Sal gets back from playing with Staind I'll try to get over and try it on some drums with cast hoops instead of my flanged hoops as I think it might be a little easier to get it exact.
Does it sound good though afterwords? Yes most definitely, and my ears are not trained enough to hear a difference of +/- .4Hz.
