Tune-Bot has been making state of the art tuning machines for drums since 2012. For years, their tool has proven its worth and people really like to use Tune-Bot products.
Frankly, this is no surprise. With a Tune-Bot, a lot of the "mystery" of tuning drums disappears. Tuning drums has always been a discipline that is difficult and takes a lot of experience. With a Tune-Bot, however, you can get going right off the bat.
The Tune-Bot gives you a precise reading of the pitch of your drum head. The Studio version also has a high range mode that is especially well suited for tuning your snare drum. On top of that, it has a nice color display that makes it easy to use.
The Tune-Bot Studio Drum Tuner, unlike its baby brother, gives you the option of saving your favorite tunings in the machine for later use. This way, you can get precisely the same intervals between your drums when you change your drum heads.
