Chromatic Tuner for Brass & Wind

This sleek, stylish chromatic tuner is designed exclusively for brass and wind instruments. Tune quickly and accurately using the internal microphone or the external clip-on contact mic (included). ACCU-PITCH verifies tuning with an audible beep. The included case can be attached to a music stand for added convenience.

Needle-Accurate Metering

In the tradition of its top-selling TU-12 predecessor, the new TU-12BW offers needle-accurate metering for precision tuning, including high-visibility sharp and flat indicators to ensure perfect tuning. Never play out of tune again!

Clip-On Mic Included

The TU-12BW comes with a handy clip-on microphone that attaches to the instrument (directly to the bell of the horn, for example, as pictured). An internal microphone is built into the tuner as well.

Music-Stand Attachment

Included with the TU-12BW is a bracket for attaching the tuner to a music stand (as pictured).
