StroboPLUS HD
I’ve been a musician for over 40 years and I can say that this is absolutely THE best tuner on the market! To call it just a “tuner” doesn’t do it justice! 
Peterson Strobe Tuners: StroboPlus HD Walkthrough (Official)
StroboPLUS HD Quick Start Video Guide
Overview
The Peterson StroboPlus HD (SP-1) is THE premier desktop digital tuner on the market! Equally as comfortable on a tech’s workbench as it is in a player’s guitar case, this tuner, with all of its features, is no exception to Peterson’s reputation for being THE most accurate in the industry — don’t let its demure palm size fool you! Players of both acoustic and electric instruments can rest assured— a built-in electret condenser microphone and ¼” input jack provide excellent connectivity. Gone are the days of having to carry extra batteries and tripping over power cables during a performance! This tuner is rechargeable via computer bus or outlet power, and its large, circular screen is easily viewed in both the darkest and brightest environmental conditions.
Features such as Auto Off, easy menu navigation, tripod mounting capability, over 90 of our Sweetened Tunings, tone generation ability via built in speaker, and a headphone output jack round out the package. Finally, future-proof updating and parameter editing is made possible by the tuner’s unobtrusive side-mounted USB jack. And for those feeling exceptionally adventurous, this tuner can be upgraded to also feature our super flexible Body Beat metronome option, along with both audible AND tactile mode operation. Hear the beat or feel it…the power is in your hands. This tuner is fit for the most discerning of players and technicians for sure!
Available Sweetened Tunings ( 93 )
Default
EQU
Standard tuning temperament suitable for regular or alternate tuning, 100 cent intervals - no Sweetening.
Guitar & Bass
GTR
Designed for use with guitars tuned to standard EADGBE. The strings are adjusted to allow for deflection by varying amounts according to the gauge of the string in each case. This improves and helps counter the often problematic “unwound 3rd string” problem on short scale electric guitars such as Les Pauls and the three saddle compromise on Telecasters.
ACU
Designed for use with acoustic guitars tuned to standard EADGBE. The strings are adjusted to allow for deflection by varying amounts according to the gauge of the string in each case. The guitar is sweetened in the same way as if tuned by the ear of an experienced musician such as James Taylor who uses these settings.
dAd
Peterson Sweetened tuning for acoustic guitar in modal DADGAD tuning with optimized fifths.
12S
Peterson Sweetened tuning for 12 string guitars with regard to the string courses.

bAS

The strings are adjusted to take into account ensemble playing which includes a stretch tuned piano.
BSn
Displays string numbers instead of note names for 4 and 5 & 6 string bass guitars ( 54321 instead of BEADG ).

Bluegrass
dBO
Compensates by making the thirds pure. This makes the sweetest sound, especially with long sustained chords where not using a Sweetener can grate on the ears due to an Equally Tempered third.
dBH
Major thirds in all three tunings are lowered slightly from Equal temperament, but not entirely beatless. This Sweetener is useful in band settings where instruments with fixed intonation are present.
bJO
Counters the typical sharp B string which is encountered when tuning a 5-string banjo without compensation with an ordinary tuner. The B is sweetened in the same way as a banjo tuned by the ear of an experienced musician.
TbO
Compensates for string deflection taking into account the different scale length and lower pitched tuning for 4 string tenor banjo.
MAN
This sweetener was developed for the mandolin, mandola and mandocello. Using it will result in perfectly tuned and voiced unison string pairs. Detuning in instruments with multiple string courses, as opposed to single strings, is much less pleasing to even the most untrained ear because both chords and melody lines are affected. The MAN setting can be used for 8-string mandolins, including Gibson Styles A and F as well as the Weber A and F series.
Misc. Stringed
UKE
The UKE Sweetener is designed for use with Concert type ukulele. UKE uses cent offsets to allow for the typical string deflection which is encountered when playing the instrument and takes scale length and intervals into account.. The tuning is sweetened in the same way as a ukulele tuned by the ear of an experienced musician.
LUT

If you want to get serious about making music that people will actually want to listen to.. it's required that you be in tune - and being in tune is complicated. WARNING: This device is not as simple as a clip on (but when I use it with the accessory clip on - it is.)
There are lots of reasons to like this.. the display is huge. the device is easy to use - yet complex if you want it to be.. it is versatile - powerful.. and awesome looking in field green - kudos for that decision.. it Rocks.. just buy this if you are serious.. or don't - and keep goofing off.. which is cool too.

Plays 4 String Bass, Upright Bass, Double Bass, String Bass, Contrabass
Basic functions are easy once video is watched...for some functions twice! Relatively easy to remember controls but it needs some practice of the functions needed. Big and easy to read display with a sensitive microphone for quiet room use. Feed through audio connections really give you confidence you are in tune. Still have to learn metrodome operation. Not the cheapest option out there but dead-on better than lesser tuners.

I am so impressed with the service I got from Peterson. I broke the clip on my 8yr old tuner not long after puchase and fixed it with a bit of wire. Finally decided to see if they could supply a new clip, which they did, very quickly and for no charge! So my old tuner is fully restored and my wife is delighted with the new StroboPLUS HD I bought her for Christmas to keep her ukuleles in tune. I can't recommend these tuners highly enough - they are accurate enough to set the intonation on guitars etc, which cheaper tuners aren't.

Plays 4 String Bass
This tuner is feature-packed and is so easy to use. Honestly, I only need it for simple tuning of a 4 string bass, and I love the fact that I can connect it inline with some effects pedals for tuning on the fly. I recommend the metronome upgrade for its ease of use and the 4 different voices available. I believe that this tuner is future-proof as well, with all the available upgrades, "sweetened" tunings that you can download and share, firmware updates and it will tune practically any musical instrument! Try it, you won't be disappointed!

Frequently Asked Questions
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 StroboPLUS HD’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 HD, 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 StroboPLUS HD offers 92 unique and very accurate “tweaks” which often make all the difference, try it!

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.
