The Cherub Tuner Clip WST-2058 is a tuner with a clear screen. With this tuner you can tune an acoustic guitar, bass guitar, violin or ukulele. By using the calibration function, you use this copy to change the root of your instrument. This allows you to set the root of your instrument between 430 and 450 Hertz. You can easily read information from the color screen. Through the clear view of information you can see at a glance how your instrument is tuned. Do you perform a lot and do you regularly play your guitar in a dark room? The LCD screen with backlighting also allows you to tune your instrument in the dark.
