Great tuner!
I had been using a Polytune, then started having some problems with it, so I got this as a replacement and really like it better than the Polytune, mainly because it gives you a much more precise reading, even down to cents as opposed to so many tuners that will tell you the string is in tune as long as the intonation is within an acceptable range of tolerance. So if one string is a little sharp, and the next string is a little flat, you got a problem! This tuner is sort of like an analog style that really lets you know where you're at. It is very silent, no click when you hit it. However, unlike the Polytune, you just hit one string at a time, which works for me. How can you go wrong with Boss?

Double duty pedal, tuner and a splitter
When I'm playing at home, I play with a Peavey Vypyr amp. Those amps have terrible tuners. Never seems to pick up the correct note on my guitar. This tuner is much better. Easy configuration, you can set it for guitar or chomatic or flat steps down, etc. The interface is super easy to read. I personally like the style where it looks like the LEDs are spinning right/left for sharp/flat, but they have the standard off from center tuning that most tuners use. All in all, this is a great tuner pedal, and I'm very happy with it. It does what it does very well. The thing I really like about this tuner is that there is an output and a bypass. Output gets cut when the pedal is active. If you are playing live, this is the one you will want to use. Bypass never gets cut. It's great for at home or if you are tuning somebody else to your instrument. But there's another awesome use for it; you can use it as a splitter and run your signal through 2 amps. This is fantastic for recording. Setting one amp up for the low end and another amp up for the high end and then mixing them together in the studio software makes for a very full sounding recording. If you want to run the same effects, put the tuner last, if you want to run different effects, put the tuner first.

Great tuner
It’s a tuner. It’s a boss. What could go wrong? This thing is great, works well, easy to use, very intuitive and easy to read. I’ve been waiting to buy a pedal tuner for some time now to replace the clip on tuners (though they still have their place) and finally decided on this especially with a recent sale. Great item, I expect it to last a long time like my other boss pedals.

Good, but maybe NOT the #1 choice for bass guitar.
It is built like a tank, it is easy to read- BUT- it is not stable or accurate enough for bass guitar from my experience. Takes far too long to lock in on low B and E strings. In live use it’s more of a get close and hope than assurance of solid tuning of lowest notes. If I fiddle with tone knobs and pickup selection it is a tad quicker, but just not practical for bass guitar in a live setting in my opinion.

Choice of two display modes to let you know if your in tune!
Everything I read says you have to have a tuner pedal on your board. So I picked this one based on other reviews. I'm a beginner intermediate player, but I understand the value of being in tune, and the aggravation you feel when what your playing just doesnt sound right. Just plug your guitar cord into the pedal and you can get yourself tuned up to exactly where your supposed to be within a minute or two... depending on the quality of the guitar and your string tuners. I have no compalint other than my $19.00 metronome and SPARK amp have tuner capabilities included. However not quite to the exact precision of the BOSS TU-3. This also has a bright display mode which can even be seen in daylight, and modes for step up and down tuning, as well as a stop scrolling lights which stop when your string is in tune, or a green light which lets you know when your in tune. If your serious about playing guitar, and you have the extra money to set out, don't hesitate. You won't be sorry.

Article reçu rapidement, bien emballé et en parfait état. L’accordeur BOSS TU-3 permet d’accorder parfaitement et très rapidement mes guitares. Il est facile à utiliser, aucun problème. Attention à la batterie fournie avec cet accordeur, elle permet seulement de bien l’essayer, donc elle sera à remplacer rapidement. Si non, tout est parfait !

Rien à redire sur cette pédale c'est du costaud et ça fait le taf qu'on lui demande c'est-à-dire accorder sa guitare ou sa basse, plusieurs modes disponibles et surtout on peut accorder sa guitare jusqu'à 6 demi-ton en dessous, comme toutes les pédales boss ça marche sur secteur ou sur pile 9 volts, achat indispensable sur son pédalboard. Il y avait un truc à redire je dirais que le vu mètre est un poil trop tatillon.

İlk aldığımı arızalı diye değişime gönderdim. Gelen ürün de aynı.. iade edip tekrar aldım 3. Gelen ürün de aynı. Sorun piliymiş arkadaşlar. Piller bitik geliyor! Kutusu zaten açık kontrol edilip pil değiştirirse gönderilmeden kimse bu kadar uğraşmayacak. Pedala diyecek lafım yok boss işte..
