Since 1948, Peterson Strobe Tuners have defined the standard in tuning accuracy. The StroboPLUS HDC encompasses decades of tuning authority and technology to deliver the ultimate strobe tuner/metronome combo!

The StroboPLUS HDC’s 0.1 cent tuning accuracy will tune any instrument with the utmost precision. Featuring a high-definition, multi-color display with variable color LED backlight, the StroboPLUS HDC display can be seen easily across the stage, bench, studio or classroom. Over 200 exclusive Sweetened Tunings® and Guided Tunings on-board accommodate a variety of instruments, temperaments, and musical genres.

The highly configurable metronome features precise 0.1 BPM adjustability in eighth notes, quarter notes, dotted quarter notes or half notes, a tempo range of 10-280 BPM, over 100 subdivisions, accent patterns, and polyrhythms. The StroboPLUS HDC can also be used to play thousands of bars of tempo maps, programmable from the Peterson Connect Web App. A single tempo map can play an entire score of meter changes, accent patterns, subdivisions, bar colors, silent bars and gradually curved tempo changes like accelerandos and ritardandos. The StroboPLUS HDC is the perfect tuning, ear training and rhythm tool all in one package!

ULTRA-HIGH TUNING RESOLUTION | Peterson Strobe Tuners

ULTRA-HIGH TUNING RESOLUTION

All Peterson products provide guaranteed tuning results to within +/-0.1 cent (1/1000th of a fret or semitone).

The StroboPLUS HDC employs Peterson's proprietary Strobo Tuning Technology to tune your instrument to an ultra-high degree of accuracy.

This level of accuracy is an industry benchmark and what has made Peterson the choice of professionals around the globe for over 70 years.

REAL-TIME TUNING RESPONSE | Peterson Strobe Tuners

REAL-TIME TUNING RESPONSE

The StroboPLUS HDC's Virtual Strobe display is DIRECTLY driven by the input signal. That means you'll see the attack, sustain, and the decay of the note being tuned - all in real-time.

Its speed of movement is in direct correlation to the distance from the target pitch and the display doesn't exhibit the often found jerky motion found in needle or LED-based tuners.

You can literally watch the strobe bands settle as you pull that note into the target pitch!

METRONOME INCLUDED | Peterson Strobe Tuners

METRONOME INCLUDED

The StroboPLUS HDC includes the most innovative and versatile metronome as a standard feature.

Hundreds of subdivision combinations, accent patterns, polyrhythms, and user-imagined tempo maps are at your disposal.

Tactile feedback is also available with the use of an optional BodyBeat Vibe Clip.

Loads of Sweetened Tunings and More | Peterson Strobe Tuners

Superior quality of both software and hardware aspects of this device. Tuner mode is awesome and the larger screen (as compared to clip-ons) is excellent. Metronome is wow! And the tempo maps are very helpful for learning complex meters and rhythms. Video tutorials are really well done and there are lots of them. Best of all is customer service!

Does my StroboPLUS HDC require calibration?

Generally, your StroboPLUS 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 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.

Peterson Connect does not detect my StroboPLUS HDC in Linux environment.

Chrome needs access to /dev/hidraw*, so either set "chmod a+rw /dev/hidraw*" or start chrome as root with the --no-sandbox option

*Some Ubuntu based distros do not allow running Chrome as root with the --no-sandbox option enabled. -Running as root without --no-sandbox is not supported. See https://crbug.com/638180. You can however run Chromium as a normal user and invoke that option.

Some users have reprted a fix by adding a new udev rule as follows: KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev", ATTRS{idVendor}=="2368", ATTRS{idProduct}=="*SEE BELOW"

* Some Peterson products operate in two different modes with individual product id's for firmware update operations. Multiple rules may need to be created. Here is the list of Peterson USB product ID's

idProduct =

Stomp Classic = 8002
StroboPLUS HD = 0003
StroboPLUS HD Firmware Mode = 8003
StroboClip HD = 8004
StroboStomp HD = 8005
StroboPLUS HDC = 0006
StroboPLUS HDC Firmware Mode = 8006

If there is trouble connecting or reconnecting as a product is switching modes, ex: StroboPLUS HDC product id 0006 to StroboPLUS HDC Firmware Mode 8006 run the command:

"sudo chmod a+rw /dev/hidraw*"

This command will solve any "waiting on user input" or if the update button in Peterson Connect is unresponsive. The command may need to be executed more than once.

What is my StroboPLUS 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 StroboPLUS 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 StroboPLUS HDC offers 219 unique and very accurate tweaks which often make all the difference.
