Just place it on the end of the neck...magic does the rest...nothing to plug in, nothing to worry about, works every time, and stays out of the way

So There Super Clip-On Tuner for Guitar is an amazing little electronic tuner that does what it's designed to do extremely well and in an easy to use compact package

Pretty awesome little tuner that does what it was meant to do perfectly

It is small and does not interfere with playing, and did not damage our guitars as had I feared
