BOSS TU-3S Chromatic Tuner Compact Tuner

World-standard tuning, now in a more compact form. BOSS's long-selling tuner, the TU-3, continues to support guitarists worldwide thanks to its durability and reliable tuning. The TU-3S maintains the TU-3's high accuracy and high visibility while achieving a significantly smaller size. When building a pedalboard using a switching system, there's no need for an ON/OFF pedal switch for each pedal. By combining it with a BOSS ES-5 or ES-8, you can create a flexible layout that makes effective use of pedalboard space.
