The Cherub WST-720B is a wired guzheng clip tuner, metronome, and pitch pipe. It’s one brand of a classic style of wired clip tuner that have been around for some time.
Americans may be more familiar with guitar clip tuners. Much like the MeIdeal clip tuner reviewed earlier, guitar clip tuners put everything into a small clip that can be attached anywhere on the instrument, drawing power from an internal button battery. The major issue with these is finding a place where the clip picks up the vibrations but where you can still see the screen. Wired clip tuners take a different approach.
Wired tuners expect you to place the tuner somewhere you can easily read them, perhaps on a nearby table or music stand, and then attach the clip sensor to a convenient place on the instrument. Guitar-style clip tuners can be left on the instrument. The Cherub WST-720B is a fine example of a wired guzheng tuner. I purchased this one in China for $13. That’s a reasonable price for the US and a little expensive for the Chinese market. Looking on TMall (in January of 2019) the listed price of ¥70 for this wired tuner puts it firmly in the middle of the price range. The all-in-one tuner and wrench from cherub goes for ¥120 while cheaper wired tuners go for ¥30-40.
