The ratchet clamp attachment safely and securely attaches to your guitar headstock so it will hang tight during live performance. It has four selectable screen position options (two vertical, two horizontal) to allow you to set your own viewing angle and can be mounted in front of or behind your guitar headstock, whether it’s right or left handed. Featuring a bright, full colour, LCD screen that's easy to read in any environment and boasting pitch calibration from 410-480 Hz to ensure you have the specific tuning range you need. The advanced tuning algorithms and piezo control of this unit allow you to tune in noisy environments and the Micro Headstock Tuner also features an auto off power function after ten minutes to save battery life.
