The BOSS TU-3S Chromatic Tuner takes the trusted reliability of the go-to stompbox tuner of pros everywhere, and scales down the dimensions to a reduced footprint that makes it even more portable than before.
As we've come to expect from the team at BOSS, the TU-3S is built like a tank - a must for those on the road. BOSS are so confident in the unit’s resilience; they've included a five-year warranty on every product. Unlike its predecessor, the TU-3S doesn't have a footswitch. Instead, it is always on and ready to go, which makes it ideal for integration into pedal switching systems, e.g. BOSS' ES-5 or ES-8. If the space on your pedalboard is at a premium, you needn't sacrifice including an essential piece of gear such as a tuner, the TU-3S does the job perfectly.
The TU-3S doesn't just cater to the needs of guitarists. With Chromatic and Guitar/Bass modes available, there is support on-hand for 7-string guitar and 6-string basses. The Chromatic mode utilises the on-board 21-segment LED's to guarantee 100% accuracy when it comes to tuning to your desired note. The Flat-Tuning mode can support up to six half-steps (semitones) below standard pitch, accurately accommodating "drop" tunings.
The BOSS TU-3S LED meter is equipped with a brightness adjustment control. Whether you're performing on a well-lit festival stage on a sunny afternoon, or in the darkest of basement venues, you can readily adjust the display for rapid visual confirmation. The Accu-Pitch Sign function provides visual verification when tuning is complete, giving you absolute confidence when you crack on with your set.
The BOSS TU-3S can be powered by an optional PSA series adapter, and even has a DC Out jack that enables you to power up to seven BOSS compact effect pedals using an optional PCS-20A daisy-chain cable.
