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”the 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.

No Regrets

By katiecooke

My guitar teacher told me that this pedal was worth every penny and that it would help a lot. He was right. It tunes very correctly, can even tune bass guitars, and silences the guitar and other pedals so you can tune. Great Buy


Good Buy

It's a tuner, it does just what I need it to do and it's pretty "idiot proof" as well. Recommend it to any gigging musician.

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.

I bought this pedal because my friend suggested it to me. So i bought it. It is a little overpriced but is worth it. It is for a quick and accurate tune on stage with out any worries... buy this bass


Excellent buy for serious musicians

All I'm gonna say is that it does something very important for serious guitarists, it takes away some of the stress we have onstage by being a very quick and reliable tuner.


TU-2 is worth every penny

By ewall09

from Canonsburg, PA

See all my reviews

I bought the pedal mainly because one of the pedals in my RP300 wouldnt work, so I couldn't go to bypass/tuner. After that happened, I just started using the tuner in my Crate FW65. That was a bit trippy, but worked. I found the TU-2 for a really great price ($60) locally, and it picks up every note in an instant. Flats, dropped tuning, everything. It's a really great pedal and it is very easy to read the LED's. I recommend the pedal to everyone. It's also a bonus that this can serve as a PS for your other pedals.


A must have

By Thaynacus

from PEI, Canada

First pedal I owned and I'm glad it was! Sure you can have a load of fx pedals, but what good are those if you go out of tune during a gig? you can tune easily and effectively during a set without having to unplug from your gear and plug into a tuner. this is fast, efficient, and tough as nails. Never had problems with it.

Tough but inaccurate.

By Tonmeister

from Los Gatos, CA.

The accuracy is +/- 3%. So if you have one string that is +3% and another one that is -3% that's a difference of 6%. It seems good, build well, but deceiving. I did not realize it until a keyboard player kept asking me to tune. So checked it with my big fancy Peterson Rack Strobe Tuner.So go with the new Korg Pitchblack Chromatic Pedal Tuner. It's +/- 1%. Better yet pony up and get a Peterson StroboStomp like I did. It's 1/10th of 1%, the same as the rack mounted Peterson tuners, wow. And, you can adjust your intonation with it too. Both will improve your guitar tone, and that is what it's all about, right.


The BEST tuner



See all my reviews

Yes, it is fairly expensive, and yes there are other tuners around, but none of them are like this. Of course, it's a BOSS, it's built like a tank, never gonna break, and it's easy to see and always perfectly tunes the guitar without any delay. Plus, when my 1-SPOT ran out of ends, I could power another pedal off of this one.


Sexy? No. Effective? Yes.

By Anonymous

from Undisclosed

I didn't really want to drop $100 on a tuner. I play acoustic guitar and my old guitar had an on board tuner. However, I just bought a Garrison G series Solid Cedar Acoustic Electric that didn't have an on board tuner. So I needed something better than the tuner which came with my starter Fender guitar from ten years ago. A buddy of mine has the Boss TU and he loves it. So, I went for it.It works. What else can I say? No waiting for the sound to register, no delay, it tunes quicker than anything else out there. I may pick up a loop station and possibly a digital delay, but I will never be pedal heavy. This will be with me forever. The fender tuner...well it's on the way out as we speak.
