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.

Done with Boss pedals, this thing is you use anything other than a boss power supply, it goes stupid. Which means my DC brick I power everything else with cant be used on this, which means chancing a battery going dead or a second plug in.

This lasted about 6 months, Boss customer service is non existent, you sit on hold 30 minutes then it says leave a message. Lousy service

        Its a tuner, there is not much to them. This one has some bells and whistles. I like it, I recommend it if you want to have a pedal tuner that can be incorporated into your setup easily.

          Would greatly prefer that the digital indicator show the note im tuning instead of string number. Very dated looking compared to the tc polytune. Tunes quickly and accurately though.

            Comments about Boss TU-3 Chromatic Pedal Tuner:

            Supposed to be the standard. Still new, and works well. Can tune up in "silence". I like that it has a generic "chromatic" setting for my cello, and then there are the presets for my bass guitar and regular guitar if'n I want.
