TU2 - COMPACT CHROM TUNER

Product Information

Where the TU-2 had a series of lights to indicate your note, the TU-3 has a labeled scale of multiple lights, each with much smaller increments between them. This allows you to be more precise while using the pedal. The TU-2 has a tuning accuracy of +/- 3 cents, which can be detectable if you have a good ear for it. The TU-3 improved on this with its tuning accuracy of +/- 1 cent, which is imperceptible to the human ear. Power Supply The Boss TU-3 retains most of the features of the TU-2, while also working to correct some design mistakes and add additional functionality. This updated version is much more versatile. The TU-3’s every feature works to streamline the classic functionality of the Boss TU-2.

For power, the TU2 can run on a dry battery or a 9V AC supply, whereas the TU2 can run on either a 9V carbon zinc or a standard 9V alkaline battery, as well as an 9V AC adapter. Activating either of these tuners when they’re attached to your pedal board couldn’t be easier. Simply stomp once to activate the tuner, this will mute output allowing you to tune in silence. When you’re done, stomp again to reactivate the output. Functions The small LCD screen on each of the pedals shows your current string and note names while you play. The TU-2 has a 7-segment display, whereas the TU-3 includes 21 segments for a more versatile display. The TU3 display on its standard setting is just a touch brighter than the original TU2, but the TU3 now has controls, allowing the user to adjust brightness as necessary. This is a welcome feature for anyone who plays outdoors in bright sunlight. Both units have their center LED light up green when you are at pitch, but the TU3 ramps this up with red confirmation lights on either side of the green when it’s satisfied that tuning is correct and stable. Accuracy Guitar Flat mode specifically allows you to flat tune, so you can drop your tunings up to six semitones. This can be great for creating unique sounds.

How does the pedal get its power? Here, you will find the difference in the type of battery that each pedal takes. The TU-3 gives you more options, but this is mostly down to personal preference. Modes Also, the new modes (10 of them) allow you to tune by string number, so you can tune more precisely. There are settings for 7-string guitars and 6-string bases, making it the perfect tuner for any of your guitars. As far as tuning modes go, both the older TU2 and TU3 feature chromatic, chromatic flat, standard guitar, flat guitar, standard bass, and flat bass tuning options, all accessible by cycling through the mode button. With this variety of settings, both options will effectively allow a player to tune to any pitch they want to play in. Which buttons on the pedal can help you tune your notes and change sound? While both the TU-2 and the TU-3 have ‘Mode’ and ‘Stream/Cent’ buttons, only the TU-3 has a footswitch thrown into the mix. This means you have more control, and you can do much more than just activate the pedal with the footswitch. Reference Pitch That isn’t the case with a mute/bypass pedal like this. You can easily change the sound of your signal without hearing any audible indicator that it’s happening, even when you hit the pedal. Powerhouse

Part of the reason the Boss TU-2 (and its successor the TU-3) appear on nearly every pedalboard you'll see is that it is reliable, accurate and has just enough capability without overcomplicating things. The LEDs oscillate at a rate indicating how close you are to the note, while a clear green light in the center tells you when your job is done for that string. The TU-2 has an eight octave range and seven modes, for standard guitar and bass frequencies and de-tuned setups down to a whole step below standard. There is even an option to set a difference reference pitch above or below A 440 (438 - 445 Hz). Beyond this, anything else is just unnecessary in a tuning pedal. Anything less than this leaves you somewhat confined in the way tune your guitar. More Than Just A Tuner The weight can also give you some indication of how portable the pedal is. The Boss TU-2 is a bit heavier at 15oz, while the Boss TU-3 is 14oz. The difference is small but may matter to you. Expected Battery Life Boss’s chromatic tuner TU-2 is a true classic from a trusted, well-renown company. The features still hold up today, even after we’ve gotten an upgraded version. Let’s take a look at the specifications that set the Boss TU-2 apart. While some pedal manufacturers automatically assume your pedal will be in a board, and thus leave the base with a bare plastic finish, both the Boss TU2 and TU3 have a rubber bottom pad, which will go a long way toward prevent the pedal from slipping around onstage should you choose to keep it separate from a pedal board.

As with the overall form factor and design, Boss didn’t really change anything between the TU2 and the TU3. As far as ease of use goes, both work in an almost identical fashion. Modes are selected through the mode button and display type is changed with the stream/cent button. Both the Boss TU-2 and the Boss TU-3 pedal have mute/bypass capabilities. When you use the pedal to bypass the signal (changing it in some way), there is usually an audible sound as you change.
