The Intelli IMT600 Guitar, Violin, and Chromatic Tuner is an intelligent, vibration sensing, clip-style chromatic tuner designed to tune guitars and violins without interference from ambient room noise - all without the use of wires, microphones or pickups. The IMT-600 attaches easily onto your instrument and picks up direct vibrations to ensure accurate tuning every time. Its unique, flexible clamp actually "feels" the instruments vibrational energy instead of relying on sound. This makes the IMT-600 the perfect tuner for a crowded stage where distracting noises can interfere with other tuners. An upgrade to the IMT-500, the IMT-600 includes a mode selector switch to choose between Chromatic, Violin and Guitar modes. The extra modes allow you to limit tuning function to a guitar or violin exclusively. The IMT-600 also features an easy-to-read LCD meter that acts like an analog meter. The backlit LCD panel illuminates making it easy to read in the dark. If youre a fan of the famous IMT-500, you will love the IMT-600 with its added features!
