The improved accuracy and tracking time over the old TU-2 is a BIG bonus. While accuracy is not too important (bearing in mind as soon as you fret a string the tuning changes slightly) it is particularly useful when setting or checking the intonation on a guitar. The tracking is FAST! Yes, there are faster tuners, but the typical 1/10 of a second response time is fast enough! Tap out a scale and the TU-3 will follow! (Which makes it a great learning tool - to check those pentatonic practice scales for accuracy!) The LED's are brighter on the new model - and there are more of them. Much easier to read at a glance. The "Acu-pitch" feature is good. By flashing, it confirms spot-on tuning. Contrary to some opinion, it is NOT a "tone sucker" - even though Boss do not use "true-bypass". (I understand they always use an FET buffer instead.) I only use a "clean boost" pedal with a Marshall tube amp (with the TU-3 in by-pass mode). The tuner has no audible effect. It's a Boss - so it will take all the normal abuse a working guitarist will give it - including the odd spilled beer! Unlike a "Pitchblack" tuner I tried recently (and returned!) there are no clunks and speaker pops when you hit the pedal. Silent operation. My only gripe is no switch. Plugging in the guitar chord switches it on. That's OK if it is used with a power supply, but not so good if you prefer to use batteries - and don't remember to unplug the guitar! Overall it's a "must have" tuner for anyone at any level. Cheaper ones just don't do the job, and spending more would be a waste of money.

I purchased my Boss TU 3 tuner after doing my research, reading the reviews and asking around. I was convinced this was the best tuner for the money, if not the best period. I went to my local Guitar Center and bought one November 2011. I was very satisfied with the product and it worked great until March 2012. This product was never abused and lightly used at best, since I play Bass and am not constantly tuning my instrument and it was only used two or three a week. Apparently the switch went bad; being so new I took the tuner back to my local Guitar Center for an exchange. Here is where the real problem lies. I felt as though the associate treated me like a moron and was only interested in defending the stores extended warranty program. After several frustrating minutes, I left the defective product on the counter and advised the associte I would never spend another dollar with Gutiar center. I am telling others to do the same as well. My business is going to local shops where there is appreciation for my business and service after the sale.

This tuner is a Boss

By

Comments about Boss TU-3 Chromatic Pedal Tuner:

Even though other tuners may tune more than 1 string and have more accuracy and features, this tuner is better built, and will last a lot longer. It has a very good buffer in it. When I put it 1st before all my other pedals, it improved my tone for my pedals and amp. It also has a lot of features and its well worth the money.

This Pedal is Essential

By

Comments about Boss TU-3 Chromatic Pedal Tuner:

Every electric player should this pedal. No other pedal gets the job done as well as the Boss Tu-3 Does. It has pinpoint accuracy with tuning and is perfect for a live setting. If I am at band practice, and my bandmates are making a lot of loud noise with their instruments, it does not matter. This thing will still pick up just my guitar with no problem. I never actually used the power supply part of it because I just use a one spot and I don't have too many pedals on my board. I used to use a behringer rip off of this pedal for $20, but it was garbage, so I got the real deal. Save your money and get this tuner, it will be the last tuner you ever buy.

Rack quality in a pedal!

By 

from Fremont NE

Comments about Boss TU-3 Chromatic Pedal Tuner:

I needed a portable tuner and had heard good things about this pedal. It was super easy to use right out of the box without reading the instructions. I usually play in D and had other cheapie tuners that did not like to read that tuning, not the Boss though it will work no matter how low you tune. This is a must own item for any player. I really love my Korg rack mount tuner but its a pain to haul a rack every where. This is the way to go!

Best Bass Tuner Ever

By 

from St. Paul, MN

Comments about Boss TU-3 Chromatic Pedal Tuner:

This is easily the best tuner I have ever used for bass, and I have tried nearly all of them out there including expensive rack mounted tuners. Most tuners take forever to read the low B string on a 5/6 string bass if they even pick it up at all but this one picks up the note right away even when drop tuned to A. I also love how the lights flash and strobe to center when you are in tune to let you know you are there. I tune my bass way faster with this tuner than the clip on tuners I have been using recently.

Good enough for the Pro's

By 

from Powell Butte , Oregon

Comments about Boss TU-3 Chromatic Pedal Tuner:

I have wanted to add one of these BOSS CHROMATIC TUNERS for quite awhile. Now I wonder why I waited so long. I've seen them on many big name players pedal boards so that says something right there. I have used clip on tuner's and little plastic box tuners and a couple of my amps have built in tuners and they get the job done but you have to stop , set up tuner, tune up , then get back into playing mode. After buying this BOSS tuner I'm just going "what was I thinking?". It is quick,easy and accurate. All the reviews I have read are very positive and used ones I Iooked at were almost full price. Make your life easier and your sound better with one of these,you will be very happy that you did.

Great Tuner, Won't Need Another

By 

from Rock Hill, SC

Comments about Boss TU-3 Chromatic Pedal Tuner:

This is a great tuner, works well in my rig. I run it from the "Tuner-Out" on my Ernie Ball Volume Pedal, so I haven't needed to use it with the bypass or anything, but it works fine. My only wish would be for it to work with dropped tunings. I use the guitar and guitar b settings (i.e. E Standard and Eb Standard) but it doesn't pick up drop tunings. Bit of a bummer, but I can easily work that last string by ear, so it's not a major problem. Overall great pedal.
