Keep your instruments in tune and playing their best with the GTA3000 Clip-On Tuner. For quick tune ups, you can select modes specifically for guitar, bass, violin/mandolin, and ukulele. Plus, the Chromatic mode gives you access to alternate tunings and enables use with other instruments such as banjo or viola. Unlike tuners that detect audio through a microphone or input jack, this tuner features a transducer in the clip that picks up frequency vibrations via contact with your instrument. This setup allows it to work with electric or acoustic instruments without the need for cables or amps, even in noisy environments. For compatibility with a wide range of instruments, the nonslip, scratch-free clip can attach the tuner to a headstock, bridge, or body. The backlit screen provides excellent visibility whether viewed in darkness, daylight, or under stage lighting. It also swivels and tilts, enabling you to dial in your optimal viewing angle. And it’s easy to get the hang of the display that lights up green when notes are in tune or white when they’re out of tune.
