Our GTA4000 Clip-On Chromatic Tuner with Multiple Instrument Modes helps keep any string instrument in tune. Its clip-on transducer picks up vibrations through the body of the instrument, enabling it to work with electric or acoustic instruments without the need for cables or amps, even in noisy environments. The high-contrast backlit screen provides excellent visibility in any type of lighting and it tilts and rotates to facilitate viewing from various angles. The clip is padded for a tight grip that preserves the instrument's finish. Discreet and light-weight, this tuner can remain attached to an instrument during performance or practice for constantly available reference.
