The bypass is a true bypass. No sound comes from your amp which is what it's supposed to do.

Bunch of different ways to tune, with flat and double flat and bass modes. Also, it DOES tune to lower tunings such as drop c!

There is 3 buttons, which explain themselves. I didn't read the manual ever and have NEVER had an issue.

It's a boss pedal. It will last longer than you or any other kind of guitar accessories you own.

I felt bad spending this much money for a tuner, but the thing about this tuner is that it does its job perfectly. I've bought a behringer plastic tuner and the thing was a joke; it broke in about it week.

Never had to deal with them, but there's a couple years guarantee with the product so they will back it up, although I don't know how you could break the thing unless you were trying to.

The lights blink and the strobe tune mode is flashy.

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

Easy to use

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

Bright display, fast response. Greatfor bass players too.

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

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

Havnt had to.

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

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

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.

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!

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.

For the price, its a great stage tuner.

Never had to use support with this pedal.

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

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.

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!

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

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.

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.

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

Very appropriate colors for a Boss Tuner pedal.

Since it doesn't appear to degrade the sound at all, I give it a ten.

Has all the features I need in a tuner. I'd give it a ten but for two things: 1. The LEDs are difficult to see when using this thing outdoors. 2. When no one is performing while I tune, the unit works perfectly. If someone is performing while I try to tune my fifth string hardly ever tunes properly.

Almost perfect!

Quality, as it pertains to the components, looks to be very good. I bought this tuner based on the apparent good name that Boss products come with. Looks like it will hold up over time.

I'd have given it a ten if the LEDs could be seen better when using the thing outdoors...and if it would tune quickly and accurately in every circumstance, which it doesn't unfortunately.

Never had to deal with Boss support so can't speak to this.

I don't have a desire to want a piece of gear just for the sake of wanting it. If it can solve a problem I have, I'll have a need for it, otherwise it can stay on the shelf at the store. Let someone else have the opportunity to buy it.

Very inexpensive for the quality.

I've always beleived that anything placed in-line between my guitars and the mixer (except the preamp w/eq) can affect the overall signal quality, but I can't hear any differences through the TU2. Absolutely quiet when switching between live and tuning modes....no popping.

The TU2 doesn't have some of the features other "high-end" stomp tuners have, but has plenty for my needs. Aside from the TU2's convenience, ease of use, and accuracy, there's a lot to be said about Boss' reputation and overall quality. That in itself is worth a lot to me as an active professional musician. Construction and materials are always top-notch and will last, as opposed to some competitors' plastic and part metal/part plastic products. I have other Boss products that I've had for years and beat to death...and still work fine.

Boss pedals are among the best out there, if not the best. Rock solid, dependable, and made to last. Five year warranty.

Yes, the TU2 is a bit pricey, but considering the "built like a tank" construction, Boss quality and reliability, I believe the going street prices are fair. It's the old addage, "you get what you pay for". I got mine for $79, so I feel I got more than what I paid for.

The only reason I rated this a 5 is because I've never had to use tech support. They could be horrible and they could be excellent.

The TU2 is a "utilitarian" design and not particularly "sexy". It's a very practical and necessary additiion to my stage setup. If looks are what you want, there are some cooler looking tuners out there, but Looks aren't what gets the job done.

It's a very versatile tuner. The one main drawback that it has is that is was one of the first "new wave" tuners out. It tunes low tunings, but not drop tunings. It has good accuracy for both bass and guitar, but it seems like you have to tune in relative quiet. Another thing that I personally find very unhelpful is that you can only tune electric instruments. My acoustic is a real pain to tune. I have to tune an electric and then tune my acoustic to the electric! So much for time saving! This tuner is really primarily for live applications. For that it has been outstanding and a life saver. For the studio, it's not so handy.

Another good quality it has is that it is built into a BOSS pedal enclosure, which makes it indestructable. It doesn't get any better than that.

I found the value to about par. It's not a real great deal, and it's not way over-priced.

No loss of tone, so that's a 10.

Hey, it tunes the guitar! Those are all the features I need. It also offers two outputs (regular and bypass), various tunings (I just use chromatic), a strobe mode, changing root tone (I don't know why anyone would want to, but you CAN), etc etc... It's got a DC out, which is fine for a second pedal or two but which can introduce noise if you string the wrong pedals to it. For instance, if you put a Loop Station on this power supply, you'll get some noise. Still that's a buttload of features for a tuner. 10.

One big-ass button! The mode, offset, etc are set-and-forget. You can use it right out of the box or read the manual (which is easy) and fiddle with the options. 10.

It's a Boss! It's bulletproof! Not much more to say... 10.

Well, this is a one-time purchase... but it costs $100, which seems a bit steep. I have not regretted it but I wish it was cheaper! Still, if I lost mine, I'd buy another at the same price.

Never dealt with Boss.

Just practical, not sexy. It's a tuner, dude.

HAs all you need to tune with.

Switch under pedal broke after less than 1 hours use during a show.

Well worth the money, at a loss as to howe it broke so fast, Always used DanElectro and changed this yearafter using a freinds pedal board setup.

Made contact, got the runaround. Never received a return call from anyone as promised. Addressed warranty and told it was my fault for "stompin" the pedal to hard !!! Yeah, my thoughts exactly if your thinking what I am thinking. Got so pissed , I threw the unit in a drawer and there it sits. $90.00 worth of of disposable income as far as I am concerned.

It's a tuner, What more can you say !!!

I have had this tuner for 5 years playing all over the US. Using it every time I play. This thing is a tank. I highly recommend this to anyone looking for a long time solution for a tuner/power for your boss pedals. The only draw back it the power supply. I have gone through 3 or 4. They don't handle the abuse like the pedal itself does.

its a tuner... it tunes

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.

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.

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.

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

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.

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.

Its perfect.

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.

6 years.

Everything music.

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

Boss pedals always hold up over time and use.

$99 bucks is well worth it.
