لم اعرف استخدامه حتى الان

視認性が良い。電源供給ができる。バイパスの切り替えができる等良い事は沢山。しかしバックパネル開けるためのネジが固着してしまっていた。日本の硬化で開けない方が良い。ペンチも壊れた。パネルも傷ついた。昔の余った人民元硬貨でやっと開いた。固着したら無理をせず返品した方が良いですよ。せっかく良い商品なのに惜しいな。

The way it shows the results is so fast and very responsive and accurate. The buffer in it is very useful.

Eccezionale! Precisissimo, veloce e affidabile.

I was on the fence about whether to choose this unit or the comparable Boss TU-3 unit. They're both the same price, and both get good reviews. I finally decided to go with this unit because it's a newer design and offered both conventional and "strobe" style tuning. The latter appealed to me because I have been using a Peterson Strobo-Clip tuner for some years, and really like the strobe tuning method. I decided I wanted a stomp-box tuner so that I could mute the sound and do quick tune-ups more conveniently than the clip-on tuner permits. I play electric bass. I found that the conventional tuning mode on this Polytune 3 pedal was just fine for my needs, and I have not yet even tried the strobe version. It also revealed that I need to touch up the intonation on my jazz bass -- playing various notes up and down the fretboard showed some deviation from the correct tuning. All the more reason not to need the micro-precise tuning of the "strobe" style display. When I say "conventional" tuning display, I mean a display that shows a needle that is positioned to the left of center if the tuning is flat, or to the riht of center if the tuning is sharp, and dead center when the tuning is correct. Some tuners have arrowheads on either side of center that light up when you are not quite at the correct tune. With this unit, the needle itself changes color, displaying as red when the note is sharp or flat, and green when it is correct. It is very quick to go through the four strings of my bass and tweak it for the needle to be green. This is a chromatic tuner, meaning it listens for the incoming note and displays what it thinks the note is. That works fine for me. It is only necessary to know that the standard 4-string bass tuning is E A D G. There are handheld (not stompbox) tuners, like the Boss TU-12, that have fixed presets for tuning a guitar or bass, but that is not generally available on a stompbox. The Polytune 3 has a "soft" pushbutton that puts it in and out of tuning mode. By "soft" I mean that there is no mechanical ka-chunk as the sawtich is operated. When the unit is tuning, the output is muted. When tuning is finished (by pressing the switch a second time), the output is connected again. There are three modes available, which are selected by internal DIP switches. The first mode provides "true bypass" switching when the tuner is turned on and off, which means that when it is not tuning, there is a direct connection from the input jack to the output jack. The second mode provides "buffered bypass," which means that the incoming signal passes through a "buffer" amplifier when not tuning. (This can be advantageous in a number of situation, especially if long cables are being used.) In both of these first two modes, the tuning display lights up only when the tuner is active and the output is muted. In other words, you can immediately tell whether you are muted or not by looking to see whteher the tuning display is lit up. The third mode is also buffered, but the tuning display remains active all the time. Thus, in theory, you can watch your tuning as you play. I have only used this unit in the second mode (buffered bypass, display on only when tuning) because that best suits my needs. There are many features which I may never use. For example, while the factory setting is A=440 Hz, it is possible to adjust this reference. Also, the unit is advertised as allowing the user to play all the notes on the instrument at once, whereupon it claims to be able to sort out which of the notes are off. I don't see any particular benefit to this for the bass, and I have read that users do not believe the tuning accuracy is quite as good in this "polyphonic" mode. Frankly, it doesn't take very long to tune 4 strings individually, and that's what I do. Since my bass keeps tune pretty well, it only requires minor tweaking to deal with room temperature change, etc. This takes no more than a minute at most. All in all, I'm very happy with my choice of the Polytune 3. It's very easy to use, has quite a readable display, and makes keeping in tune during a show very simple. I suspect the competitive units out there (like the Boss TU-3 or the Korg Pitchblack) are also fine, which may make the choice more difficult in this category. All I can say is that I think people would be happy with this well-made unit, so hopefully that will help with the decision.

Extremely accurate tuner, great for setup work , intonation and can imagine it would be a great stage tuner as well. Highly recommended
