De Ibanez PU3-BK Chromatic Clip Tuner heeft geen selectietoetsen of vermogensschakelaars nodig. De efficiënte en nauwkeurige tuner wordt automatisch ingeschakeld wanneer deze op de kop wordt geklemd en schakelt automatisch uit wanneer deze wordt verwijderd. Het LCD-scherm knippert in verschillende kleuren, afhankelijk van de toonhoogte.
It's not easy to choose a guitar tuner out of the many out there but I went for this one because, well... I'm a bit of an Ibanez afficionado for one and also the price was right. But mostly, because I liked the display graphics: clean, clear and colorful. After testing it out, I still like the very small form factor and the bright LCD display. One comment on the display, though: it has a very small viewing angle, so it has to be viewed straight-on for optimum clarity. I checked it against my Boss pedal tuner and must say it's pretty accurate. The fine colored indicator lines allow for precise tuning and the automatic on/off switch function is a very practical addition - no need for an on/off switch, just clamp it on and it works. Nice! One major flaw I didn't notice when ordering, is the fact that the display 'head' turns on just 2 axis. It sits in a horizontal position on the guitar head-stock and can't be turned upright to a vertical position, so it has to be viewed at on it's side. It would have been the perfect little tuner to have in your pocket for those unexpected occasions, were it not for the tilted position of the display when clipped on the guitar. I tried every possible spot on the head-stock of my Ibanez but it always sits on it's side. Other than that little inconvenience, I'm certain to have made the right choice.
