BOSS TU-3S Chromatic Tuner
BOSS TU-3S Chromatic Tuner
Item may be on display!
(Incl. Taxes & Shipping Cost)
The BOSS TU-3 is the world’s go-to stompbox tuner, trusted by players everywhere for its reliable operation and bulletproof durability. Scaled down in size, the TU-3S gives you the same industry-standard performance in a tiny footprint that saves precious pedalboard space. The display and tuning functions are identical to the TU-3—the only thing eliminated is the pedal switch. Always on and ready to go, the TU-3S is perfect for use with pedal switching systems like the BOSS ES-8 and ES-5, and ideal for any setup where space is at a premium
Features:
- Tuning performance in a more compact size
- 21-segment LED meter with brightness control
- High Brightness mode enhances meter visibility outdoors
- Accu-Pitch Sign function provides visual verification when tuning is complete
- Chromatic and Guitar/Bass modes, with support for 7-string guitars and 6-string basses
- Guitar Flat mode supports “drop” tunings up to six semitones below standard pitch
- Powered by optional PSA-series adapter; DC Out jack for powering up to seven BOSS compact effect pedals via an optional PCS-20A daisy-chain cable
- Dimensions: 73 mm / 2-7/8" W X 84 mm / 3-5/16" D X 56 mm / 2-1/4" H
