Korg GACS Guitar Tuner 3D Visual Meter

The Korg GA Custom Guitar Tuner reimagines what a compact tuner can deliver, centering its design around a revolutionary 3D visual meter that brings depth and motion to pitch detection. Unlike conventional flat-needle or segmented LED displays, the 3D meter uses visual effects to convey tuning information in a way that is both engaging and highly readable, even at arm's length on a music stand or pedalboard surface. With tuning accuracy rated at an extraordinary +/- 0.1 cents, this tuner provides the precision demanded by professional musicians and studio recording sessions where even subtle pitch discrepancies are audible.

Despite its advanced accuracy, the GA Custom maintains a slim, flat form factor with a generously sized screen that keeps it portable enough for gig bags and pockets. Three selectable meter display modes let you switch between visual styles depending on your preference or lighting conditions. The built-in high-sensitivity microphone extends its usefulness beyond electric guitar and bass to acoustic guitars, ukuleles, and orchestral instruments — no cable required. For players who take pitch accuracy seriously and want a tuner that is as visually informative as it is precise, the Korg GA Custom delivers on both fronts.
