    Core Electronic Tuner ET20

    I like the tuner. It fits well on my violin (unlike my previous electronic tuner, which was meant to clip onto a guitar). It seems both sensitive and stable, two opposite things. I can't explain how it can be both. Anyway, I like the tuner. And for a violin, I would recommend this tuner over most of the other electronic tuners, which are mainly meant to fit on a guitar, and so don't fit well on a violin. Also, the display is intended primarily for a violin (not a guitar), something which makes me feel very comfortable with THIS tuner, over most of the other electronic tuners. I would recommend this tuner for anyone who needs a tuner specifically for a violin.
