As a beginner, I've always struggled with tuning my drums. My biggest problem was the flood tom, which almost always had a very long and out-of-tune hum, which I foolishly tried to hide by adding more dampening.
To my surprise, the solution was simple. I got a set of Evans Clear reso heads, and the Evans Black Chrome set, which are in themselves much easier to tune.
I got this tuner at a whim, not knowing much about the underlying concept, but after doing some research, my life has been made a lot easier.
The tuner is very well built, it's quite heavy, which is to be expected. My expectation is that I will never need to buy another tuner for my drums again.
It's easy to use, the tension gauge works very well and is very sensitive, and it reduced my time spent tuning significantly.
I would also like to add that tuners are an absolute must have if you are doing live drum recordings, and my sound engineer was very pleased with the tone I was able to supply when I went in the studio.
Overall I would definitely recommend buying this if you can afford it. If you take care of it, then it will most likely last a lifetime.
