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.

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.

What is my tuner’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!

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 tuner?

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.

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.
