FOUR TUNING MODES Digital: arc gauge with 25 color-coded indicators. Green when in tune, yellow in the intermediate zone and red when off. Indicators move with fluid animation for greater visual precision. Meter: high-precision linear meter showing deviation in cents with smooth and continuous movement. Analog: classic needle gauge inspired by vintage galvanometers. The needle responds to sound with natural movement and gently returns to center when no signal is detected. Manual: generates reference tones per string for tuning by ear. Reflects the active capo position when set.
