Boss TU-03 Clip-on Tuner & Metronome TU03

Love the way it clips to irregular surfaces like the scroll on the neck of my cello. Very easy to tell when I'm in perfect pitch. The reference pitch tone generator and metronome make this the real deal when it comes to a complete tuner.

This is a nice little tuner with good function. Used for bass and cello, it gets the job done well. The clip is strong and has a protective grip. It's easy to position in odd ways if needed and it's screen is well visible in dark situations. The metronome is efficient. I wish the battery lasted a bit longer but it isn't bad to be fair, use a good one and carry extra. Boss products are generally dependable and this is a well made little guy.

Affordable Accurate Compact Clip on Tuner

I use this product for all of my acoustics, electrics guitars/basses, and even my upright bass! Really perfect for any stringed instrument that causes a vibration. Even works with brass and woodwinds oddly enough. Really affordable, has lasted me a long while. Only downside is that it needs batteries but that's an easy fix by just having a few in your bag. All in all, accurate and easy to use.

Can't figure out which string is being played.

This thing literally can't figure out which string is being player. It switches up strings and will skip over strings and their tunes, its ridiculous. I will tune the B string and this thing will skip from G straight to E and when I slowly tune back down it will skip straight back to G.

Decent Tuner (per novice guitarist)

Am using this to tune my guitar and it's fine for that. I l like the color zones = red for out of tune, green for in tune. Makes it easy to see. Wish it had more angling options, so you can see the face more easily when tuning. But I'm new to this so could be me getting the placement wrong...(also has metronome, but am not using it yet so can't review that aspect.)

Does Its Job Well

I wanted a not-too-fancy clip-on tuner that included A = 432 in its range. It was easy to set the non-standard reference. I like the display-- it flashes bright green when the string is tuned properly. It also can sound the A note if desired.So far I haven't used the metronome feature, and it's too soon to judge how sturdy it is. But it's made a great first impression!

Excellent training tool

After seeing my instructor use this tuner/metronome, I just knew I needed it for my at home practice sessions. Easy to use, solid tool all around.

Good practice tool.

I like the combination of tuner and metronome in one small package. Easy to read plus you can twist the display around to be viewed from almost any angle. Only minor complaint is that the size of the clip makes it a little difficult to clip on to the headstock of a couple of my guitars (PRS headstock in particular) as it is just slightly too wide to fit between the tuning pegs and there is only minimal real estate to clip it elsewhere. It still fits on them, just not as securely. Fits fine on my Fenders and Gibson though.

My purchase was possibly defective

The three stars are for the features and the well lit screen but the meter never stopped in the middle to display that you're in tune. The lights continuously teetered back and forth very, very fast. I would use my other Roland tuner (and others) to confirm I was in tune yet the TU-03 would not stop teetering sharp and flat. In the end I returned it for another item and Sam Ash made this very simple. Maybe it was defective.

Will rock this tuner until the plastic degrades

This tuner never leaves my guitar. The screen is visible in any type of lighting and it can clearly pick up my strings even with other background noise. Easily one of my better gear purchases
