This Hello Kitty-themed tuner may look playful, but certainly isn't a toy. It comes with a contact microphone that allows you to tune up at the same time as other musicians - great if you're part of an orchestra or ensemble.
Tuners don't come more compact than Korg's Magnetune. Attach it to the tuners or strap buttons of your guitar by means of its magnet, and tilt it any way you like for an optimal viewing angle.
The Korg CM-200 BK is a black piezo contact microphone that can be connected to any tuner with an audio input. Simply attach the microphone to the bell of a brass instrument, or to the bridge of a violin, guitar or ukulele.
This clip-on tuner for your ukulele is shaped like the headstock of... A ukulele! The string indicator LEDs on the Korg Headtune HT-U1 clearly indicate which string you're tuning, and a LED meter bridge assists you in the tuning process itself.
The Korg CM-200 WHBK is a contact microphone for wind instruments and string instruments like violins, guitars and ukuleles. Attach it to your instrument and the piezo pickup registers the sound waves and transmits them to your Korg tuner.
