Title: Should have bought this years ago... a must!
Review: A friend of mine brought one of these over to my recording studio one night when I was recording a demo for his band. This thing blew me away! It is extremely accurate at measuring drum head tension at any point on the drum head. This allows you to accurately tune a head. I've been playing and recording for years and years and I have gotten really good at doing this by ear. However this takes my ability to get really close and lets me get dead on. My band musician friends all hear the difference. This is the best drum invention since the drum key. I got this through Amazon and of course it got here fast and in perfect condition. I love this thing!
