At first, I did not like the glaringly-bright orange backlight for the strobe display, so I sent it back to the factory for some modification. At the suggestion of Customer Service Representative Sue Haslam, they installed red LEDs and a brightness control, which makes my unit far more versatile and comfortable to gaze at for long periods in subdued ambient lighting, like in a studio, and bright enough to read in a sun-filled room when the need arises.

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.

Frequently Asked Questions
Does my AutoStrobe 490-ST require calibration?
Unlike more modern Peterson strobes, legacy models such as the Peterson 400, 420, 450 and 700 do require occasional calibration.
If you require service, please open a support ticket and return the tuner for repair.

How do I read a strobe display?
Adjust your instrument until the pattern is as close to still as possible. Strobe displays are 'real-time' and extremely precise. They require very fine tuning adjustments to stop the display because the frequency/pitch of any instrument is never totally stable.
You'll quickly learn to read the display, make the most precise adjustments and appreciate the high resolution that only a Peterson provides.
