EASY INTONATION | Peterson Strobe Tuners


Use StroboSoft to adjust more than just your tuning. Save time and money by intonating your instruments at home!

Intonate your electrics quickly and easily using StroboSoft's Visual Intonation Guide that employs a 2-step visual indicator system to help you achieve the ultimate in accuracy when setting up your instruments.

The built-in INTONATE function will visually assist you while intonating your instrument. The LED on the selected string will fill with color when you are in the proper octave-just isolate the strobe display and you're done! (Deluxe feature only.)

SIMPLE INTERFACE | Peterson Strobe Tuners


Large, illuminated arrows indicate whether your tuning is flat or sharp to assist in tuning direction and make large adjustments easier to discern.

Target Tune switches the NOTE/OCTAVE window functionality over to allow user viewing of what note they are trying to achieve rather than what note they are currently at.

For example, INPUT will allows display the chromatic input signal but switching it to TARGET and engaging the manual note select option will hone StroboSoft to only look for the selected value and ignore any other frequencies.

This is a great feature for tuning to an exact frequency or cent offset.



Sweetened Tunings™ compensate for the inherent inadequacies of string, brass and woodwind instruments by making minute adjustments in pitch for each instruments standard tuning. Sweetened presets can optimize an instruments playability and tone.

Almost 40 preset Sweetened Tunings™ are available in StroboSoft Deluxe for a variety of instruments. Built-in support for Buzz Feiten (BFTS) equipped instruments is included. (Deluxe feature only.)

LARGE DISPLAY | Peterson Strobe Tuners


The large display provides all the traditional tuning information including the note and octave location for the note being tuned.

The multi-view window allows the user to control whether relating note/octave details are displayed as cents (away from target note/octave), Hertz or MIDI note number equivalents.

You can use this window to view offset values in when creating your own stretch tunings or analyzing other preferred tunings.

PLUG AND PLAY | Peterson Strobe Tuners


StroboSoft provides everything you need to accurately tune and even set-up your guitar or bass without the need for any expensive additional sound cards!

You can successfully use StroboSoft with your stock hardware by plugging your instrument into the computer's sound card input.

StroboSoft's selectable sampling rate will support all sound cards up to 96kHz.

Use the stereo/mono selectors to tune two instruments at once! Have an electric guitar on the "L" channel while an acoustic can be hooked into the "R", each with individual settings.

SPECTRUM ANALYZER | Peterson Strobe Tuners


The spectrum analyzer offers a real-time view of the spectral components on the input signal.

The red 'X' indicates the fundamental note being identified by StroboSoft.

The analyzer can be extremely useful in finding noise present in the incoming signal helping to identify reading difficulties. Harmonic detections and visual recognition of fundamental frequencies can also be seen in the analyzer view.

LINEAR PITCH GRAPH | Peterson Strobe Tuners


The Linear Pitch Graph can be very useful when practicing intonation training or trying to measure performance with an instrument.

The graph will display your performance instantly and provide visual feedback that can help isolate problem areas.

Ideal for use practicing chords, embouchure, or vocal training.

Harmonic viewing can also be enabled for a complete linear representation of the incoming audio spectrum. (G3, D3, and A2 shown.)

OSCILLOSCOPE | Peterson Strobe Tuners


An oscilloscope is a useful instrument for testing signals because it allows you to see the signals at different points.

The oscilloscope allows the user to view the actual shape of the signal coming into StroboSoft.

Use it to help isolate noise issues such as pick-up noise that could cause tuning problems. Tuning issues due to old strings or new strings that haven't been stretched properly can be quickly viewed and identified.

TAP TUNING UTILITY | Peterson Strobe Tuners


For instrument builders, tap tuning is used to adjust the tunings of the various parts of their instruments - soundboards, backboards, air chambers, and apertures - to make instruments that not only sound good, but sound good consistently - instrument to instrument. Tap tuning ensures that the parts of the instruments are tuned to each other as well as to concert pitch, imparting a timbre that is not attainable by merely assembling an instrument.

Adjustable threshold triggering allows complete control of the tuner in any set-up or tuning environment. Average Taps function employs statistical techniques to reject bad "measures" such that a single poor measurement won't affect the results. (Deluxe feature only.)

 | Peterson Strobe Tuners

"My first tuning was of my Warwick Thumb bass. I used a sweetened preset and easily tuned the bass. It was very stable compared to other tuners that I have used. I then played with the intonate function on the tuner and discovered that my harmonics were in tune.

I can see that this tuner would be very useful to people setting up their own intonation on stringed instruments. This is a tuner that I will be using for a long time!"

- Spence and UberPro at UberProAudio

"Best tuner I've ever used, bar none. I know it sounds crazy to get excited over a tuner but it's exciting in a really weird way to take an "in tune" guitar (with a different tuner) and fix the tuning so that it's REALLY in tune.

Great for tuning, great for intonation, simply the best tuner I've ever used (I know I said that already, but it's true)!"

Recently bought the full desktop version for setting up my guitars/intonation etc. The strobe tuner and the features are wonderful. Only cons are that the software is extremely dated and needs bringing forwards into the modern day.
Easier said than done I understand and above all, if you are looking to acquire the best possible gear for the best possible results for setting up guitars, there is no other alternative.
Peterson seem like a great company so I'm confident that the updates will come.

I have used a Boss TU-12 since the late 80's.
Before today, I had never found a common tuner that touched it.
The physical needle tuner ruled, in my life, over 30+ years.
I have never been able to afford the amazing physical Peterson Strobo tuners, they are worth every penny.

Here is my experience with Strobosoft 2.0 today.

I have owned my Acoustic guitar for over 14 years, it's the first instrument that I tuned with the software.
Even with months old strings, I have never heard it sound this pure, this perfect.

My recordings will be forever changed.

Thank you for continuing the Peterson family tradition of innovation, by creating this affordable, and incredibly accurate software.

Before you spend your money on the windows desktop version of Strobosoft, be aware that this version does not have anything extra compared to the ipad version, so if you already own that, no point in buying this.
For the money, I expected the product to be on par with the iPad version, which I already own. A bit of a disappointment.

I bought this product for the taptuning feature on it, and that seems to work properly.
But from time to time the app crashes unexpectedly ( I work with OS), and also the display could have been bigger, some 'knobs' on it are pretty small. But the 'analog' feel of is is nice, and once I found out how it works (The manual af Siminoff really helps) it really helps me with my instrument building !

I am using the strobosoft 2.0 to tap tune a mandolin I am building. After a little trouble with getting the converter (anolog to digital) for my Mac, I am on my way. The software is simple to work with is delivering expected results. Now, If I can only get the neighbor to stop running his skidloader in the backyard I can make some progress on the mandolin. The backup beeping is driving me crazy.

The core functionality of this software is excellently done. It is a great tuner, in the end.

That said, The UI of the standalone app is a little frustrating to me. I have a Chapman Stick, so I have a stereo input, ideally. I am fairly certain that I cannot select two channels of audio at once, however. Not a huge issue, since switching is possible, but it adds friction. I also wish that the metaphor of hardware was abandoned, at least a little. The layout of controls seems cramped especially since the window can't be resized.

I'm using this on an M1 Mac.

Developer updates to the product are sluggish, but I note that there is a new MacOS version that solves the problems many of us were experiencing.

For many software tuning use cases, Strobosoft is now superseded by tuners freely available as mobile phone apps, or included with modelling software. The mobile version of Strobosoft is a better proposition and I use this all the time, being as the full software version took so long to be updated by the developer.

Peterson's hardware tuners are world class but the developer has a slow update cadence for Strobosoft, which is out of touch with what people want. On top of this, the market for a software tuner has radically changed, albeit vanishing, as many people get sufficient utility from mobile apps etc.

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.

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 StroboSoft 2.0?

Your StroboSoft 2.0 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 StroboSoft 2.0 detection AND display accuracy is 0.1 cent due to its high definition display which is the highest of any tuner on the market.
