KORG Sledgehammer Pro - 3D Clamp Tuner with ±0.1 cent Accuracy

The KORG Sledgehammer Pro is a clip-on chromatic tuner for guitar and bass that combines ultra-sharp readouts with professional accuracy of ±0.1 cent . Its 3D visual meter offers superior visibility in any environment, and the shuttle switch on the tubular body allows for one-handed power, mode changes, and calibration, even while playing. The clip features an articulating arm and ball joint that ensure a firm hold and complete angle freedom on the headstock.

Main features

• Ultra-high precision: ±0.1 cent for fine adjustments with studio-quality accuracy.
• High-visibility 3D display: clear and quick reading on stage, in rehearsal or in the studio.
• Three metering modes: Regular, Strobe and Half-Strobe.
• One-handed operation: Shuttle switch for power, modes and calibration without releasing the instrument.
• Robust and flexible clip: high clamping force plus movable arm and ball joint for adjusting position.
• Useful features: memory backup that preserves settings, auto-off to save energy, and reference calibration.
• Range and scale: chromatic from A0 (27.50 Hz) to C8 (4186 Hz) in equal temperament (measurement with sine wave).
• Calibration: A4 = 436–445 Hz in 1 Hz steps.
• Battery life and power: Up to approximately 14 hours of continuous use with 1 CR2032 battery (included for verification).
• Ultra-compact format: 62 × 62 × 53 mm and 28 g to always carry in the case.

Benefits for the musician

• Faster, more confident tuning: The 3D display and strobe modes help you nail the tone with minimal hesitation.
• Frictionless operation: Switching modes or recalibrating with the “shuttle” is instant, ideal between songs.
• Live stability: The clip keeps the tuner steady even with movement on stage.
• Optimized consumption: automatic shut-off and coin-cell battery reduce downtime and maintenance.
