BOSS Chromatic Tuner Compact Tuner TU-3S

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

World standard tuning made more compact. BOSS's long-selling tuner "TU-3" continues to support guitarists around the world due to its durability and high tuning reliability. The TU-3S maintains the high accuracy and visibility of the TU-3, but is significantly smaller. When building a pedal board using a switching system, ON/OFF pedal switches for each pedal are not required. By combining it with the BOSS ES-5 or ES-8, you can create a flexible layout that effectively utilizes the space on your pedalboard.
