Jonathan says, "They don't get anymore indispensable than this. These tuners should be mandatory for every member of a band that is regularly gigging around town. Not only is the TU-2 a fantastic tuner, it is also a money saver. After plugging in the optional Boss PSA120T power supply, I can daisy chain out of my TU-2 into all of my other Boss pedals. Forget inconsistent batteries, forget multiple power supplies. Just plug into the TU-2."

The TU-2 Chromatic Tuner incorporates BOSS' world renowned TU-Series tuner technology into an ultra-convenient stompbox design. For the first time ever, guitarists and bassists can now tune their instruments with BOSS accuracy with just a single stomp.

- Mute/Bypass select for silent tuning with a single stomp
- 11-point LED indicators and new "stream" meter display tuning discrepancy via speed and direction of LED's (speed of LED movement gets slower as pitch becomes more accurate)
- 7-segment LED displays string and note names, easily visible on dark stages
- Seven easy tuning modes include Chromatic, Guitar Regular, Guitar Flat, Guitar Double Flat, Bass Regular, Bass Flat, Bass Double Flat
- Tuning mode setting and display style choice stored in memory
- Adjustable reference pitch from 438 to 445Hz
- Footswitchable Tuner Off mode preserves battery life by disabling LED's
