Planet Waves Chromatic Headstock Tuner
March 25, 2009
This small device tunes by sensing vibrations from the instrument, which are picked up by a built-in piezo transducer. The CHT worked great on a recent gig in a noisy room.
Attached to the headstock of a Joe Veillette Jazz 14 guitar, it provided clear sharp/flat indications that made it easy to tune quickly and accurately between songs. I
also really like how the how the display switches from red to green when
you're up to pitch. This a cool product!
