I just received a Peterson Strobotuner 490ST a couple of days ago and just used it for the first time today. I have been tuning pianos for over 30 years and this tuner is a "dream"! I used it on a 5'8" grand piano and the stretch tuning set the temperament just the way I like it. It cut at least an hour off my regular tuning time and I'm looking forward to using it on different kinds of pianos. I am very particular in my tuning and I think this unit will remove a lot of my "stress" on getting the right sound. I have tuned the piano I tested this unit on many times and this particular piano sounded the best it's ever sounded. Very pleased!!

Autostrobe 490-ST is a very precise tuner and can be a valuable aid in the work, even for an expert tuner technician with a very refined ear. It also allows you to perform a piano tuning satisfactorily and in a shorter time than you can in other conditions.
Sometimes the reading of the stroboscopic disc is a bit 'difficult and the image is not clear. Probably this also depends on the quality of the instrument to be tuned. Perhaps the problem could be solved by using a suitable microphone.
Autostrobe 490-ST can also exercise the human ear to improve the ability to perceive even the smallest nuances of sound and allow you to make tunings always specific to each instrument as each has its own timbre, its voice and its defects like every single human being.
Even if we are at very high levels, that research continues ...
