The GTA4000 chromatic tuner is well-suited for guitar, bass, ukulele, mandolin, banjo, and similar instruments. Its tactile transducer picks up vibrations directly through the body of the instrument. This means the GTA4000 works with acoustic or electric instruments without the need for cables, even in noisy environments. The high contrast screen offers excellent visibility in any lighting. The secure clip is designed to grip tight without marring finishes, and can be left on during performances for instant reference.
