Space-conscious musicians no longer need to compromise on tuning accuracy with the BOSS TU-3S, a compact powerhouse that brings professional-grade performance to even the most crowded pedalboards. This miniaturised version of the legendary TU-3 maintains all the essential tuning functions and crystal-clear display that have made BOSS tuners the industry standard worldwide.
The TU-3S operates with the same bulletproof reliability that players have trusted for years, but in a significantly smaller footprint that maximises your pedalboard real estate. By removing only the pedal switch, BOSS has created an always-on tuner that’s perfectly suited to modern pedal switching systems including the ES-8 and ES-5.
This streamlined approach makes the TU-3S an ideal choice for professional setups where every square centimetre counts, whilst maintaining the rock-solid durability and precision tuning that has established BOSS as the go-to choice for musicians across all genres.
