A tribute to the legend
Cherub is well-known for making high quality digital tuners and metronomes for decades. 

About 17 years ago, in 2005, Cherub released the first "clip-on" digital tuner WST-550G, which has been a hit to 
guitarists in the world. It was the very first time that we could tune the instruments in such a simple way. 

In 2022, we bring a new clip-on tuner WST-551C with Cherub's latest tuning technology to musicians.
It's a tribute to the legendary “Clip-on tuner”.

accurate and ultra-responsive tuning performance for musicians. And the reference pitch can be adjusted easily
