At Winter NAMM 2010, Boss announced the TU-3 Chromatic Tuner ($160.50 MSRP) as an updated followup to the pedalboard standard TU-2.

The TU-3 guitar and bass stompbox tuner adds functional enhancements to the original’s specs, like the new high-brightness meter mode that improves visibility under bright sunlight, and a 21-segment meter light that provides accurate and visable tuning. Likewise, the new Boss Accu-Pitch function visually verifies when the target pitch is attained, and the sound output is muted while the tuner is on so that you can tune silently while on stage.

Housed in a rugged Boss stompbox chassis, the TU-3 also features Chromatic and Guitar / Bass tuning modes that allow you to tune by string number, supporting seven-string guitars and six-string basses. The TU-3’s LED meter and arrow indicators clearly show when the instrument is in tune, no matter what light you view it in. It also looks really cool.

Meanwhile, Flat Tuning mode lets you calibrate the TU-3 for tunings up to six half-steps below standard pitch, and the tuner’s reference pitch can be adjusted over a range of 436 to 445 Hz.

Boss expects to ship the TU-3 this month. For more information, visit rolandconnect.com.
