Pitch Grandma's tuning fork in the garbage and jump into the 21st century with Korg's Sledgehammer Pro Clip-On Tuner. Sitting securely on your guitar or bass headstock, it has a 3D Tubular LED Visual Meter for easy viewing and a shuttle switch on both sides for one-handed operation.
Its moveable arm and ball joint offer a free range of angle adjustments for easy access to calibration (436 to 445 Hz), and meter selection (regular, strobe or half strobe). The Sledgehammer's +/-0.1 tuning accuracy will keep those of you with perfect pitch out of the nuthouse. Its auto power-down function saves the drain on its 14-hour battery life, while its memory backup saves your settings.
