Feature:
Bright display, fast response. Greatfor bass players too.

Quality:
Bullet proof-metal construction. The others are cheapy plastic.

Value:
Nice price for this quality tuner. Even the "stream" mode is only available on more expensive rack units.

Desirability:
Boss hit a home run with this tuner, its a must have for any roady.

Sound:
Transparent, as it should be...

Support:
Havnt had to.

Overall:
I think the quality and price cant be beat.

Feature:
Love the fact you can tune down so easily.

Quality:
Very well made.

Value:
Very inexpensive for the quality.

Desirability:
Well made.

Sound:
This is a great tuner.

Support:
Boss is #1 in my book!

Overall:
I will never need another tuner.

Feature:
A terrific, easy to see color display screen. It delivers that perfect tuning you are looking for.

Quality:
Built solid

Value:
I think that it's a little expensive for a tuner.

Desirability:
I've never seen a tuner in pedal form.

Ease of Use:
Easy to use

Overall:
Very nice. It's a great tuner. My guitar sounds great after using this pedal. Good work Boss.

Feature:
While this has a lot of features, I prefer the standard tuner best. This pedal tunes Bass guitars, 8 string guitars, and standard guitars. It is VERY versatile!

Quality:
It's Boss. I am definitely putting this on my pedal board. I love it. I bought it to replace the tuner built into my Crate GLX1200 head. On my crate tuner, it has 3 indications of tuning. This is a very detailed tuner. Great buy, would buy it again if need be.

Value:
This is very similar to the DigiTech Hardwire series tuner, but this one looked cooler to me, and I bet is the same quality of the DigiTech.

Desirability:
Very appropriate colors for a Boss Tuner pedal.

Sound:
Well, it depends weather or not your running it on output, or bypass. Bypass lets you tune, with your signal still running. You still hear your guitar when tuning. As for just the standard out put, This is a great feature to this pedal. I have heard of lots of guitarist using this for onstage tuning, and a silencer. As will I.

Ease of Use:
Very easy to use. Step on the pedal, and you hear silence, and you can tune your guitar to the 100% perfect pitch.

Support:
Haven't needed it. Doubt I won't!

Overall:
I would buy this again if need be. I love it, as it tunes your instrument PERFECTLY!

Feature:
The different tuning modes are very useful when bored and you want to change something, as long as it is not your sound. Never had any issues with the hardware.

Quality:
The main reason I got this tuner is that I needed a tuner I could see in very low light. The TU-2 is also a very fast tuner. I usually take about one second per string. It also works very well on 5 string basses, down to the low B. This pedal has served me well over the past 5 or 6 years. I use it all the time at home, in the studio, or on stage.

Value:
For the price, its a great stage tuner.

Desirability:
Try finding someone willing to sell a TU-2. That will tell you how much people really like this tuner.

Sound:
Nice and quiet bypass mode. For best results, use a 9V battery. This pedal is not very immune to power supply noise.

Ease of Use:
Slight learning curve to comprehend all the modes. I was up and running right out of the box. It took a little while to comprehend all the modes this tuner can do, but it was time well spent. While the LED lights are very easy to see on a dark stage, there is one I should caution you about. There is one LED in the lower center of the effect face that indicates the sharp version of the note in chromatic mode. I have had the awful experience of tuning between songs and mistakenly tuned two of my strings ( A and D ) to A#, D#. After much confusion and outright anger, the tuning was fixed, but man... did that suck!

Support:
Never had to use support with this pedal.

Feature:
It does for bass & guitar. I'd say its a very very good tuner. One of the best i've used out of handheld tuners and other footpedal tuners.

Quality:
Its perfect.

Value:
The price is fine, whatever. Its a good tuner, plus it pretty much just silences your and guitar if you're not using anything else.

Sound:
The sound quality is pretty much over-all perfect. It pretty much gives a perfect sound if you tune it perfect to 440.

Ease of Use:
The use of it is pretty simple. No one should really complain about it unless you're lazy, but its pretty simple like any other tuner but gives great tune sound.

Overall:
Its a perfect tuner. Gives you a perfect tune, and its as simple as could be.

Feature:
mutes signal when tuning so you can silently tune in between songs on stage - a must!!

Quality:
Boss pedals always hold up over time and use.

Value:
$99 bucks is well worth it.

Feature:
its a tuner... it tunes

Quality:
Boss is awesome. I don't have too many pedals but I've owned boss and digitech pedals and boss is about 2000 times better in terms of durability. It won't break... ever.

Value:
It's kinda expensive for just a tuner, BUT its accurate, its easy to use, it's very durable, and you'll never have to buy another tuner again.

Ease of Use:
I doubt you'll have to read the manual to know how to use this thing, but if you do, it is always there if you need it.

Overall:
Again, expensive but worth it. Also it's a chromatic tuner so you can tune to different tunings other than standard tuning, such as drop C. Buy it.
