Does my StroboClip HDC require calibration?

Generally, your StroboClip HDC will not require calibration and should remain perfectly accurate if it has not been damaged.

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 long do I need to charge my StroboClip HDC if the battery dies?

Your StroboClip HDC will give roughly 5 minutes of tuning time after a 1 minute charge.

10 minutes of charging will give roughly 1.5 hours of tuning time.

45 minutes of charging should fully charge the StroboClip HDC and allow up to 6 hours of tuning time.

What is the battery life of StroboClip HDC?

The StroboClip HDC should operate for roughly 6 hours of tuning time, dependent upon color choice and brightness.

The colors red, green, and blue use only one LED driver and therefore require less power allowing for longer use before depleting the battery.

White uses all three LED drivers at full power, using the most amount of battery power and will reduce the amount of tuning time available.

Brightness values will also affect the battery life. Brightness may be set via the Configuration Tool in Peterson Connect.

My StroboClip HDC is charged but will not turn on. What do I do?

If your StroboClip HDC is non responsive to the Power/m\Menu Button, and it is confirmed that the battery is charged, please use the Reset Button located on the rear of the tuner.

To activate the Reset Button, insert a pin or straightened paper clip into the hole in the back of the tuner. You will feel a slight depression and click of the Reset Button. Hold the Reset Button in the depressed state for 3 seconds then release.

Your Power/Menu Button should now function normally.

How do I read a strobe display?

Basically, the strobe image appears to travel to the left if your instrument is flat of the desired pitch and to the right if it is sharp. On earlier models such as the StroboStomp 1, StroboStomp 2, VS-1, VS-II and V-SAM, the strobe image travels upward if your instrument is sharp and downward if your instrument is flat of the desired pitch.

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.

Is the accuracy the same for all Peterson tuners?

Yes, the accuracy is within 0.1 cents (1/1000 of one semitone) as with all Peterson Strobe Tuners. An important thing to note is that Peterson Strobe Tuners have ultra high definition displays, so not only are they highly accurate in detecting a note but they have the ability to display that accuracy. Other products claim accuracy but do not have the high definition screen to display the level of accuracy in which they claim. If you cannot see the accuracy, it is of little value. Only Peterson provides High Definition Strobe Tuning.

What is my StroboClip HDC’s Sweetened Tunings feature all about?

A Sweetener is a set of cent offsets or a deviation from generic Equal Temperament interval spacing traditionally used in tuning. Tuners made by Peterson, including the StroboClip HDC, contain many choices of Sweeteners, in other words, several presets with differing interval spacing relevant to the instrument being tuned. If you’ve never been happy with how your instrument tunes up with your present tuner, a Sweetener could be just the thing to change that without any modifications whatsoever. The StroboClip HDC offers 65 unique and very accurate tweaks which often make all the difference.

How accurate is my StroboClip HDC?

Your StroboClip HDC is accurate to 0.1 cent (1/1000th of a semitone). It’s important to note, that unlike other tuners which list the detection accuracy as the main specification, the StroboClip HDC detection AND display accuracy is 0.1 cent due to its high definition display.

I often tune my acoustic instrument in a loud environment. What's available to help with that?

When tuning an acoustic instrument in an environment where you cannot control the background noise, like at a gig or loud band hall, a vibration pickup is a very nice alternative to using the built-in microphone.

A Peterson TP-3 clip-on tuning pickup is a very versatile device with a 1/4" connector that can be clipped onto any portion of the instrument that vibrates, such as the headstock of a guitar or the bell or lead pipe of a horn.

A Peterson Pitch Grabber Mobile Tuning Clip utilizes a 1/8" connector for use in mobile phones or tablets with software tuners.

For instruments with a flat resonating surface, you can use a suction cup tuning pickup to reduce ambient noise interference.

Windows 10/11 presents "USB device can't be recognized" error when I plug in my tuner.

If Windows 10 or 11 presents the error "USB device can't be recognized" when your tuner is plugged in, this is usually caused by a corrupt automatic driver installation.

A restart of your computer will usually solve this issue.

  • Click Windows/Start button
  • Select Power
  • Select Shut Down
  • After your computer powers off, restart your computer, plug in your tuner, and the USB drivers should install automatically.

    Which browsers support Peterson Connect?

    Google Chrome, Chromium, Microsoft Edge, Opera, Vivald and Comodo Dragon all support Peterson Connect which is built on webHID, a feature more and more browsers are adopting.

    How do I find out how far out of tune my guitar is in cents?

    Pluck a string and adjust the cent value by simply adjusting the cent control until the strobe image is stationary (only fluctuating around a fixed position and not shifting in one direction over time). In this case, you are tuning the tuner to the instrument. When the image comes to rest, the accompanying numeric cent display indicates the distance from 00.0 cents.

    The following video shows this process using a StroboPLUS HD.
