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 high definition. They require very precise 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.

What is my ’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 , contain many choices of “Sweetness“, 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 offers unique and very accurate “tweaks” which often make all the difference, try it!

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.

Does my tuner require calibration?

Generally, your tuner 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.

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.

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

A Peterson TP-3 clip-on tuning pickup is a very versatile device 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.

How accurate is my ?

Your 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 detection AND display accuracy is 0.1 cent due to its high definition display which is the highest of any tuner on the market.

Try cleaning the input jack with a small brush or q-tip lightly dampened in alcohol. The microphone is disabled when a cable is connected to the input jack. The StroboPLUS HD may occasionally mistake any dirt or debris in the input jack for a physical connection.

My LCD screen is going dim.

The LCD screen of your Virtual Strobe Tuner may go dim for a short time right before the battery runs out. Although the batteries may not be old, check to see if replacing them corrects the LCD brightness.

Powering the unit with the provided or suggested power supply can also help determine if the LCD screen is in fact failing. If the LCD is still dim after changing the batteries or plugging the unit directly into a wall outlet, please open a help ticket so we may assist you further.

I charge my StroboPLUS battery to full but it switches to one bar when I disconnect.

Some of the latest run of StroboPLUS tuners ( May/June 2015 ) may incorrectly read the remaining battery life. Our engineers are working on a firmware update to address it. Your battery is actually charging to full in an hour or two but when you unplug, the software doesn't read the remaining battery life correctly. Other than the incorrect graphic, your StroboPLUS will work normally and the battery will last as long as any other StroboPLUS. We will send an email to all registered users when a new firmware update is ready.

Update: July 9, 2015 - This issue has been resolved as of firmware update 1.1.6.

Does Peterson Connect only work with the Google Chrome Browser?

No, but it works better with Google Chrome!

Before June of 2015, Peterson Connect required the download and installation of a separate piece of software in order for your products to communicate with the Peterson website. This software existed for both Mac OS X and Windows. Recently, the Google Chrome browser has offered developers new tools to make tasks like these much easier for the user. Converting Peterson Connect from a stand-alone application to an app for Google Chrome greatly simplifies the Peterson Connect installation and user experience for the majority of our customers.

Those who prefer a different browser can design sweeteners and presets in any browser. Only the data transfer to your tuner relies on Google Chrome ( as opposed to downloading and installing a stand-alone application ). All of the other functions of the Peterson website will work in any browser. However, using Google Chrome to configure your tuner provides a quick and seamless link between programming and transferring data to your device. Chrome acts as the USB Driver for your tuner. - a USB driver that also happens to be a very useful browser in many respects. In the future, as technology allows, this will work with all browsers.

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.

I've registered my StroboPLUS HD or Stomp Classic but the website will not allow me to configure or update my device.

In order for the website to be able to program your device over the USB connection, it first has to "register" the internal ID, so it can perform the USB communication.

Although you may have registered your warranty and serial number, until the site gets a read on your connected device for the first time, it cannot pair that physical device to your warranty registration and serial number and therefore will not allow it to be programmed. This is called 'pairing'.

Be sure to be logged in to the same account in which you registered your warranty. If using Peterson Connect for Google Chrome, you will be asked to 'pair'
