The best part: these tuners work great. They even come with a battery. (Cue the "Wow!")
Includes five modes: C, G, B, V, U (chromatic, guitar, bass, violin, ukulele) to cover the gamut of stringed instruments. It also works great on mandolin, banjo and nearly any other stringed instrument.
BATTERY INSTALLATION: Remember the old saying "Righty tighty, lefty loosey?" Well, forget that when installing this battery. To open the back panel turn the lip COUNTER-clockwise.
