A pedal tuner equipped with a high-performance "ULTRA BUFFER". Despite its compact model, it achieves ultra-high precision of ±0.1 cent. It has 4 types of meter display modes that can be set according to the player's style. What is "ULTRA BUFFER"? ULTRA BUFFER is a buffer that improves the sound quality during bypass and maintains the sound quality even when using long shield cables to connect to the tuner or when incorporating the tuner into a complex effects board. Most electric guitars are equipped with passive pickups with high impedance output. When using a shield cable, the sound quality (usually the high frequencies) deteriorates at about 5m, and the longer the shield cable, the more it deteriorates. ULTRA BUFFER prevents signal degradation even when using long shield cables and maintains a clean and clear sound quality even when the pedal is off.
