Got a Drum Dial recently in a local sale, finally got around to trying it.
Using the guideline settings from DD, I found that I had tuned by ear to exactly the DD suggested range. Not sure if this speaks better for me or for the DD
but I definitely found it useful to be sure all the lugs were set to the same tension.
I could see how the TuneBot would offer even more precision, but the Drum Dial seems to work well enough for my needs. As still a relative noob I appreciate tools that also educate, and the DD seems to be a great way to learn what different tensions do in relation to tuning, and how great a difference a quarter turn of a tension rod can make.
I like it.
