I am really sorry to have to submit a negative review of a Peterson tuner, but the StroboClip HD is the **** WORST **** Peterson product I have ever had!... I have three other models that work great... The large tabletop model with the blue rubber cover, A flip-style Peterson, the Peterson app on my phone, but now this StroboClip is **** WORTHLESS JUNK! ****

It is flimsy and easily breakable, It does not respond with the same fluid motion that my other Peterson's do, and I don't trust it for accurate tuning.

(I would NEVER use this StroboClip to do guitar or bass setups!)

I don't believe that Peterson actually built this unit themselves... I believe they farmed it out to some other (offshore?) company to built them to a cheap price.

The on/off switch is tiny, and flimsy. The push buttons are not intuitive and are not usable onstage.
I have kept this unit in a small, hardsided, zippered case. I have had to replace the battery twice. I believe it turns itself on when shaking in ...

I still have the first StroboClip from ten years ago, and still works great! They are the best tuners I have used in almost 40 years of playing music.

This tuner is tremendous. It takes just a little to get used to, like anything else, but then you find yourself dialing in a tuning in no time. Plus, all the preprogrammed sweeteners for open tunings or drop tunings. The StrobeClip HD makes it a piece of cake.

After all that, if you have a problem, the support staff is professional and incredibly helpful.

Support could not be better!

I've purchased a bunch of tuners over the past 45 years. I've owned/still own a few rack mounts, floor pedals, etc...I liked/loved most of them, but they were all missing something.......Some were a little bit off, but looked great and were quality solid. Others, tuned (almost) perfectly, but were plastic, w/ low light LEDs. Of course, I wanted accuracy and something solid, that would stand up to daily, hard use.....
The Peterson StroboStomp HD was introduced to me by my Bass Guitar Tech. He got a raise..... I bought the StroboStomp HD and I still can't believe how reliable this tuner is. I'm still using the first one that I purchased, back in August 21, 2020, from Elderly Instruments. I bought another one, that is in storage at my band's studio.
Pull the trigger.....you will not be disappointed. Check out Petersons other gear too. This company knows what they are doing. They know how important, dependable gear is to us musicians. They always hit that mark and more. (A lot more) ...

Have upgraded from the iOS software to this one. Very pleased that it provides a simple solution to my tuning needs. I mostly play 12 string acoustic and wanted the sweetened tunings.

I also bought the case for it. While the tuner is great, the zipper pull on the case was off the first time I unzipped it. While I was able to re-attach it fairly easily, this shouldn't happen on a brand new case. It was the Peterson case recommended for this stroboclip.

On the recommendation of the Vice President of Reuter Organs I purchased this tuner prior to a complete tuning of a four-manual 73-rank Schantz pipe organ. Truly an outstanding machine! The strobe function was very useful in the 16' and 8' octaves, particularly when the "tuning stop" was a bit distant. That the tuner can produce sound clear up to the top of a 2' stop was tremendously helpful. Those last few notes can be difficult to hear when tuning to the octave below. Tuning a unison to the machine was very easy and accurate. Being able to adjust pitch in tenths of a herz is extremely important in organ tuning. It simply has everything I could want for organ tuning.

I used standard tuners before I got the Strobostomp HD. I compared the sound of my Les Paul when tuning with the standard tuner with tuning with the Strobostomp and was amazed. It is unbelieveable hat much better the guitar sounds with the on spot tuning of the Strobostomp (I did not even use sweetened tuning yet). The difference is remarkable in clean sound but especially dirty sounds - no matter if using the overdriven channel of a tube amp or a pedal - just sound so much clearer and more powerful. Tunig is fast and the strobo is easy to adapt to even though I had been using standard meter and LED Tuners for years.

Pros:
best tuner I ever had, better than other tuning pedals or built in tuners (Kemper, AxeFXIII, GT1000)
fast and very precise
makes your guitar sound simply better
battery change is easy (no screws) and the additional DC out is very useful

Cons:
The device is a about 1/2 inch longer than standard Boss, EHX or tc pedals. Keep this in mind when desiging you board layo ...
