The Eno ET-36 is a small, handy clip-on tuner for those on a budget who require a basic function tuner that provides accurate results. With an LCD display measuring just 23mm x 27mm, the ET-36 has selectable pre-set tunings for Guitar, Bass, Violin and Ukulele, as well as a Chromatic (universal) setting that picks us any note between A and G, including the sharps and flats in between. Powered by a single CR2032 watch battery, the strong spring clip attaches to the headstock of your guitar or bridge of your orchestral instrument, and picks up the vibrations of the instrument when a string is plucked or bowed. The LCD display then accurately shows on screen if the open note of the string is sharp, flat, or spot on in tune. If perfectly in tune, the screen shall illuminate green and a needle indicator shall point dead centre, displaying the note in bold. If sharp or flat, the needle will point right or left of the centre respectively, and dictate the intensity of the tuning by pointing far right or far left if vastly out of tune, and move closer to the centre the closer in tune you get. The clip itself has rubber on all contact points to prevent damage to your instrument, and the main head of the tuner is also pivoted to allow you to minimally adjust the angle of the screen.
