Precise tuning with a tap of your toe.

The Boss TU-2 Chromatic Tuner lets you shift to bypass mode for silent tuning with a single stomp. An eleven-point LED stream meter makes it easy to see when you're in tune (the movement of the meter slows the closer you get to pitch). Seven different modes provide options for both bass and guitar and a seven-segment display makes string and note names readily visible on dark stages. Footswitchable Tuner Off mode preserves battery.

  • BOSS world-renowned TU-Series tuner accuracy in a convenient stompbox design
  • Mute/Bypass select for silent tuning with a single stomp
  • 11-point LED indicators and new "stream" meter display tuning discrepancy via speed and direction of LEDs (speed of LED movement gets slower as pitch becomes more accurate)
  • 7-segment LED displays string and note names, easily visible on dark stages
  • Seven easy tuning modes include Chromatic, Guitar Regular, Guitar Flat, Guitar Double Flat, Bass Regular, Bass Flat, Bass Double Flat
  • Tuning mode setting and display style choice stored in memory
  • Adjustable reference pitch from 438 to 445Hz
  • 8-octave tuning range‚ÄĚthe widest in its class
  • Footswitchable Tuner Off mode preserves battery life by disabling LEDs

If you are reading these reviews chances are you are on a quest for the best tuner for the money. I own the Boss TU-2, the Fender PT-100, and the Korg DTR 1000 rack mount tuner. All of them do their job, but I thought it might prove helpful to share my experiences and offer a side-by-side comparison of these three products.The Fender PT-100 is the least expensive of the three and it is a good tuner. It works very well for guitar, but it has a hard time finding the notes for bass, especially the low E, and it doesn't do well at all with the low B of my five-string. The display is bright and easy to read in any light and is solidly built. It has a mute feature that I like, but the mute mode developed an annoying, rather loud hum, which is almost as annoying as tuning up in "live" mode.The Boss TU-2 is far superior to the Fender tuner. Like all Boss stomp boxes, it is heavy and very solidly built. It locks onto a note much more quickly than the Fender unit does and the independent sharp/flat indicators are very handy for truly precision tuning. I leave it in standard mode all the time and it works well with both bass and guitar. It has a bit of trouble with the low B on the five-string bass, but finds it eventually even when it is not shifted into bass mode -- a few taps of the "mode" button is all it takes to switch modes, but I need my reading glasses to read what mode it is in and I am too lazy to bend down to hit the button anyway. The Boss unit is more than twice the cost of the Fender unit, but well worth it in my opinion.The Korg DTR 1000 is an outstanding tuner and the best of the bunch. It finds any note, guitar or bass (even the low B) very, VERY quickly -- so quickly that my guitar player watches the alpha indicators change while I play (I leave it on all the time) and then gives me a hard time if I hit a wrong note. Like the others it has a mute feature for silent tuning, and in strobe mode it is very fast and easy to get in perfect tune plus the strobe effect offers a bit of a light show as well! If cost is a concern, the Fender or Boss units will do the job very well, and I would recommend saving up a few extra bucks for the Boss as it is a more versatile and better tuner in my opinion. If you want a really great tuner and money is not a major concern, you will not be disappointed with the Korg DTR 1000.

On the "local" club scene this tuner appears to be the industry standard, so I bought one untested. If you really care about the consistency of your sound though, you'll get a Peterson, which is far more accurate, albeit with a little learning curve. There's so much variance in what the TU-2 tuner says is a perfectly tuned string that a novice should be able to hear the difference. A bad unit perhaps? Nope. I tried a few owned by friends and the results are the same.For budget conscious persons I recommend the BOSS TU-12H for about 30% less (I have a 20-year old one that's way better than the TU-2). But truly, Peterson rules this world. Spend the dough and get a StoboStomp2, I bought two of them after using one for the first time.The BOSS TU-2 is also not true bypass and will rob a little bit of your sound if used inline rather than off a tuner out.All that said, I have found a use for my TU-2... I use it to get a cool sound out of my 12-string. Strings tuned to the same note sound so much different that it gives a 12-string some cool sounding textures. However, it's never consistent... I just need to take the time and program the custom tuning into my StroboStomp2.

To clear up the accuracy debate.

By Rickles

from NJ

See all my reviews

To clear up the accuracy problems, this tuner is rated for +/- 0.3 cent. Not (%)Percent(%)... This is more accurate than any trained ears can hear. I have not used this tuner but I'm attempting to clear up some facts about tuner accuracy. A cent is 1/100th of a hert. Concert pitch (standerd) tuning refers to A at 440hertz. Hertz. In scientific terms. 100 cents make up a hert. Trained ears can usually tell the difference of about 5-10 cents. Not .03 of a cent like this tuner can. I can not say anything about the way boss TU-2 tracks, but there's no reason to buy a +/-.01 tuner over a +/-.03 tuner. This tuner should satisfy all of your accuracy needs.

Inacurate, noisy, tone sucking, overhyped

By Anonymous

from Undisclosed

I bought this under the assumption that it was one of the best and i wish i could have my money back. I get noise when tuning through my effects chain and I don't find the tuning accurate at all. I'll usually tune my A string and tune the rest by ear so that at least MY guitar is in tune with itself if not standard 440 A. Also my tone takes a serious step down when I have this in line, forcing me to unplug from my amp and plug in directly to avoid having it in my chain... what's the point???I'm very picky about my tone, and small changes that a lot of people ignore bother me a lot. This tuner does not live up to my standards. I'll be selling it to one of the endless fans who don't mind or can't hear it's problems and buying something else.

An excellent tuner. I don't know how anyone can complain. I'm sure there are some faulty ones out there, but it is really a superior pedal. Many pro players use it so that should tell you something.


The best tuner you can buy for the money

The Boss TU-2 is the best tuner I've ever owned. Easily read on stage, accurate tuning, and its well constructed. I know several musicians who use and love it. You can't go wrong with this unit. I think boss owes me a check for this review.


Great, but could be cheaper.

I got this a couple months ago and immediately fell in love with it. It's fast, accurate, and makes playing shows a lot more smooth. The only problem I really had with it was it's cost.. A little too expensive, but it's still worth it.

I've used this tuner on stage for 7 years, 3 nights a week. It's durable,easy to read and completely accurate.


Best tuner... for anyone.

By xKBCx

from Calgary, AB. Can.

This tuner is amazing, i've used it twice and i just picked one up. It's a little pricy for some, but looking at the construction this is no suprise. If you play live, you can tune all of your strings within seconds and you don't have to un-plug. Plus, the tuner does not add hum while playing due to the fact that it is bypassed when not engaged.

I can't really ask for anything else with this pedal. It, like other Boss pedals, is near indescructible. It tunes extremely well and very accurately as well. I can't think of anything else I could really demand from this pedal. It does everything it needs to do, and nothing less. The price is steep, but a pedal tuner is worth it. I still can't believe there are self respecting guitarists who still use handhelds on stage. Oh help me, I can't even picture it. That's how reliant I've grown on this one.

I bought this tuner, after I saw it at my church. I LOVE IT. It is well built, has great qualities, and is at a very good price. I love this tuner. It is well built, which is a lot coming from me. My tuner has been through crap, and it still is going stong. My only problem is that if you leave any cables plugged into it, that is drains the batter. I suggest getting the AC power adaptor for it, which will also run you other Boss pedals. This is the perfect tuning pedal, or guitar and bass. I strongly suggest it!!


Best tuner I've ever had

By Tom-ON9g4

from Bronxville, NY

I use this for a bass. I've had many, from conventional Boss and Roland tuners to the vibration-sensitive kind and this one is more precise and reliable. The foot pedal allows for quick checks between songs. The only issue is that it uses up a 9 volt battery fast and I've been through one electrical adaptor already which failed after 6 months for no apparent reason. But overall this the best tuner I've found
