“Sledgehammer is a line of small, clip-on tuners mounted on the guitar’s headstock. The Pro version s additionally equipped with an extremely precise interface known from Korg’s professional rackmount model.”

“The tuners receive the instrument’s vibrations through a sensor mic built into the clip. It does not require any cables, thus enabling us to tune any given instrument.”

“Korg Sledgehammer series tuners are very useful and easy to use. They offer everything you would expect from a modern tuner: stable performance, very clear display and proper sensitivity.”
