EXACTLY what I wanted (and needed) in a tuner
First, let me start out by saying that I probably could have bought the original TU-3 (non- Waza Craft version), and been sufficiently pleased. However, anything that promises premium quality and uncolored signal has my attention, whether I can tell a difference or not. And hey, it just looks cool! The top feature I needed in a tuner pedal, aside from accuracy, was speed. I've always used the clip-on style, namely the Snark SN-8, which promises to be fast and tight. It's a good tuner that has served me well without any complaints, but I felt like I should invest in something of a more professional grade. I narrowed it down to this TU-3w, along with the TC Electronic PolyTune 3, the Korg Pitchblack Custom, and the ultra-affordable Snark SN-10S. It was tough to choose, as these are all well-regarded tuners. The PolyTune's ability to tune all strings at once was interesting, but a lot of people said they ended up checking each one individually anyway. Plus, since my primary use will be with a bass guitar, I doubt that I'd actually use the polyphonic method. A lot of folks said the display was sometimes more difficult to see in polyphonic mode (since it has to display all strings at the same time). The Korg Pitchblack was a contender simply because it's one of the tried-and-true tuners, and the Custom version just looks cool, but nothing really stood out otherwise. I really like the display on the Snark SN-10S (and so did a ton of other reviewers), and even though most reviewers said it was fast, accurate, and built like a tank, there was just something weird about it being priced at a fraction of the others (and I don't know why that would be a problem!). Since I couldn't make up my mind, I defaulted to this one since the TU-3 seems to be "the" industry standard tuner -- everyone either has one or has used one. I'm really glad I did, and I won't think twice about the others. Of the clip-on tuners and tuner apps I've used, nearly all of them seem to have some level of lag. Worse, many of them give a slightly different reading for the same note that you've just tuned. Speed means nothing when you can't get a consistent measurement. This TU-3w picks up and locks onto a note faster than I can look at it; tracks the tuning smoothly and steadily in absolute real time; never second-guesses itself; and it's so easy to read. If there's a better way to tune, I can't imagine how. Even if I spent more than I really needed to for the Waza Craft edition, I'm extremely pleased with every penny that I invested, making it one of my most prized tools in my gig bag.

Probably the best pedal tuner available.
The Boss TU-3W is my favorite pedal tuner, period. The tuner has a flexible input and output interface, much like the TU-3, allowing you to either pass signal while you are tuning or mute while tuning. Compared to the TU-3, the TU-3W has improved visibility and seemingly more accuracy. On dark stages, the blue lights are easy to see and light up well. The pedal tracks perfectly and rarely (if ever) cannot register pitches, even extremely low bass notes. The pedal is finished in a gorgeous, stealthy black. The switch works fantastically with the famous Boss smooth-touch. While the price isn't cheap in comparison to other tuner pedals, the quality and functionality makes up for the price difference. The only thing I would change would be to add a mute function that doesn't turn off the tuner.

Boss TU-3W Waza Craft Pedal Review
I recently purchased the Boss TU-3W Waza Craft Tuner pedal after having used the Peterson StoboStomp HD pedal for a few years. I gave a 5-star review of the Peterson StoboStomp HD pedal which is well deserved. As I wrote in that review, the Peterson is the best for tuning accuracy. It is the most accurate pedal out there. However, do you really need that kind of accuracy on a pedal? Is it even beneficial? One thing I noticed when I started using the Boss TU-3W Waza Craft tuner pedal is that it seems to do its job in a quicker way than the Peterson pedal. The TU-3W seems more suited to situations like band rehearsals and gigs. The accuracy of the Peterson StroboStomp HD is great, but really, that extra accuracy is not really needed when you’re just tuning up at a gig or rehearsal with your pedalboard. Unless you also need that tuner for working on intonation and setups, it’s really not necessary. For as little as most of us need an accurate tuner for setups and intonation from time to time, there are some smartphone apps that are just as accurate as a strobe tuner, these cost from five to ten dollars each. The TU-3W simply zeroes in on the note, lets you know when you’re in tune with the brightly illuminated light, and that’s it, you’re in tune. Assuming that your guitar is properly intonated, that’s all you need. The less complicated, the better. The buffer on the TU-3W is very good, and it sounds great on my 12-pedal pedalboard. In all fairness, the buffer on the Peterson Strobostomp is also very good. The advantage of the TU-3W is that switching from the buffer to true bypass is much easier to do on the fly, whereas on the StroboStomp the switch is in the battery compartment and more difficult to get to. Between the BOSS TU-3W and the Peterson StroboStomp HD, they are both excellent pedals and you won't go wrong with either one. It's a matter of preference at this point. I found the large number of "sweeteners" on the Peterson to be a distraction, and I honestly never used them other then messing around with them a few times. I found the BOSS TU-3W to be able to get the job done quicker then the Peterson. The Boss pedal design and form factor is better designed and more intuitive, and is also easier to install on a pedalboard than the Peterson. On the other hand, I know players who absolutely love the many sweeteners on the Peterson, as well as the higher level of tuning accuracy for doing setups. It all depends on what you need the pedal for. You won't go wrong with either pedal. The Boss TU-3W Waza Craft is a great pedal and is recommended.

Best tuner I've ever owned
I'd rate it more than 5 stars if I could. A little pricey yes but worth it. Amazing tuner. Tuned my 6 string guitar to drop F tuning just to see if it could and it did. Most of my other tuners got sloppy any lower than drop c. Super bright lights, easy to see works for my guitars and my bass guitars. Buy once cry once you will never need another tuner again

Typical Boss quality
I've wanted to try one of these for a while, but didn't want to spend the money on a pedal that I already have covered. I received a gift card, so I decided to give it a go. First off, it is a good looking pedal. The sleek black with the blue and green lights is nice. I only look at it when I need to tune, so it's not a big deal, but I thought I'd mention it for those that are concerned about it.. The functionality/accuracy is also great. I compared it against a few clip on tuners, another tuner pedal, a phone app, and an amp based tuner for 4 different guitars. It was right on with all of those, but showed a little more accuracy for the fine tuning. I cant speak to any battery life concerns due to my use of a power supply on my pedal board. The ease of use is on par with any other pedal (plug in and step on the switch). I expect this one to last a while, just like the few other Boss products I've had in the past. The price is a bit higher than other tuner pedals, wo find it on sale, or buy used, if you really want one.

Favorite tuner I’ve used
First off boss makes great pedals that last. The waza craft is their top of the line for sure. Now that I use lower tunings cheaper tuners do not work. This easily picks up low g on my 7 string and could easily pick up lower. Very accurate and intuitive. Also the blue is easier to see than the red on the standard version. I notice no tone issues when I test it in the chain and take it out.

best in my opinion but not perfect
good tuner but 2 demerits. 1st, forget about using the 9v battery. I've burned through 2 already, over 2 nights, using it for maybe 20 min. only to find out that its energized and a hog at that the entire time you're jack is plugged in to the input. Wouldn't trust that onstage. 2nd, the lock in tuning mode aint so accurate. It tuned properly only when I used the strobe like mode and waited after plucking the string. The lock in mode seemed to be way off in my book, as well as accepting the value right when open string is plucked or picked, that goes for the harmonic as well (electric guitar). I suppose that's not the tuners fault, but the lock in value which might be convenient is not accurate, but that also is probably true with all tuners and more dependent on how incremental your hands can turn the tuner and the tuners gear ratio. I still prefer it hands down over the competitors. Its not too busy, it has good lighting, ez to read, and in the strobe like mode it locks in better than the competitors. One of em being the Peterson which is the gold standard for accuracy, imho, but I find it way too sensitive and time consuming, that is by the time you're close to locking in, the signal has alread decayed
